The First Rocket Launch from Cape Canaveral

Image
A new chapter in space flight began in 1950 with the launch of the first rocket from Cape Canaveral, Florida: the Bumper V-2. Featured here, the Bumper V-2 was an ambitious two-stage rocket program that topped a V-2 missile base with a WAC Corporal rocket. The upper stage was able to reach then-record altitudes of almost 400 kilometers, higher than even International Space Station. Launched under the direction of the General Electric Company, the Bumper V-2 was used primarily for testing rocket systems and for research on the upper atmosphere. Bumper V-2 rockets carried small payloads that allowed them to measure attributes including air temperature and cosmic ray impacts. Seven years later, the Soviet Union launched Sputnik I and Sputnik II, the first satellites into Earth orbit. In response in 1958, 60 years ago today, the USA created NASA. via NASA https://ift.tt/2DK5Jax

The Wikipedia article of the day for October 1, 2018 is Duncan Edwards . Duncan Edwards (1 October 1936 – 21 February 1958) was an English footballer who played for Manchester United and the England national team. He played 151 matches as one of the Busby Babes, the young United team formed under manager Matt Busby in the mid-1950s. Born in Woodside, Dudley, Worcestershire, Edwards signed for Manchester United as a teenager and went on to become the youngest player to play in the Football League First Division. As the youngest England player since the Second World War, he played 18 times for his country at top level. In a professional career of less than five years he helped United win two Football League championships and two FA Charity Shields, and reached the semi-finals of the European Cup. He was one of eight United players who died as a result of the Munich air disaster; he survived initially but succumbed to his injuries in hospital two weeks later.

The Lonely Neutron Star in Supernova E0102 72.3

Image
Why is this neutron star off-center? Recently a lone neutron star has been found within the debris left over from an old supernova explosion. The "lonely neutron star" in question is the blue dot at the center of the red nebula near the bottom left of E0102-72.3. In the featured image composite, blue represents X-ray light captured by NASA's Chandra Observatory, while red and green represent optical light captured by ESO's Very Large Telescope in Chile and NASA's Hubble Space Telescope in orbit. The displaced position of this neutron star is unexpected since the dense star is thought to be the core of the star that exploded in the supernova and created the outer nebula. It could be that the neutron star in E0102 was pushed away from the nebula's center by the supernova itself, but then it seems odd that the smaller red ring remains centered on the neutron star. Alternatively, the outer nebula could have been expelled during a different scenario -- perhaps eve...

The Wikipedia article of the day for September 30, 2018 is Jean Bolikango . Jean Bolikango (1909–1982) was a Congolese educator, writer, and conservative politician. He was Deputy Prime Minister of the Democratic Republic of the Congo (then Republic of the Congo), in September 1960 and from February to August 1962. Enjoying substantial popularity among the Bangala people, he headed the Parti de l'Unité Nationale and worked as a key opposition member in Parliament in the early 1960s. Beginning his career in the Belgian Congo as a teacher in Catholic schools, he wrote a novel and worked as a journalist before turning to politics in the late 1950s. Though he held a top communications post in the colonial administration, he became a leader in the push for independence. After the Republic of the Congo became independent in 1960, he promoted both a united Congo and strong ties with Belgium. The President of the Congo posthumously awarded Bolikango a medal in 2005 for his long career in...

55 Nights with Saturn

Image
For 55 consecutive nights Mediterranean skies were at least partly clear this summer, from the 1st of July to the 24th of August 2018. An exposure from each night was incorporated in this composited telephoto and telescopic image to follow bright planet Saturn as it wandered through the generous evening skies. Through August, the outer planet's seasonal apparent retrograde motion slowed and drifted to the right, framed by a starry background. That brought it near the line-of-sight to the central Milky Way, and the beautiful Lagoon (M8) and Trifid (20) nebulae. Of course Saturn's largest moon Titan was also along for the ride. Swinging around the gas giant in a 16 day long orbit, Titan's resulting wave-like motion is easier to spot when the almost-too-bright Saturn is digitally edited from the scene. via NASA https://ift.tt/2P1qe3H

Wikipedia article of the day for September 29, 2018

Image
The Wikipedia article of the day for September 29, 2018 is John de Gray . John de Gray (died 1214) was a medieval English Bishop of Norwich. He was employed in the service of King John even before the coronation, for which de Gray was rewarded with various ecclesiastical offices, culminating in his pro forma election to Norwich in 1200. He continued in royal service after his elevation to the episcopate, lending John money and undertaking diplomatic missions on his behalf. In 1205 John attempted to further reward de Gray by making him Archbishop of Canterbury, but a disputed election process led to de Gray's selection being quashed by Pope Innocent III in 1206. Stephen Langton was consecrated as archbishop against John's wishes, triggering a long dispute with the papacy. The pope imposed various sanctions on England and John. In 1209 de Gray became governor of Ireland for John, and spent until 1213 attempting to impose royal government there on the Anglo-Norman barons and the...

The Wikipedia article of the day for September 28, 2018 is Myst IV: Revelation . Myst IV: Revelation is the fourth installment in the Myst series, developed by the French video game publisher Ubisoft. First released on September 28, 2004, it uses pre-rendered graphics and digital video, as in Myst III: Exile, but adds real-time 3D effects. The player is sent to question the sons and recover the daughter of Atrus, a man who creates links to other worlds by writing special linking books (illustration shown). Development of Revelation lasted more than three years, requiring as many as eighty Ubisoft employees. The original score was written by Exile's composer, Jack Wall. Musician Peter Gabriel lent his voice and a song to the audio. Overall, reception to the game was positive; reviewers lauded the visuals, sound, and puzzles, but some took issue with the control scheme. Revelation is the last game in the Myst series to use both pre-rendered backgrounds and full-motion video.

The Wikipedia article of the day for September 27, 2018 is The Sunday Times . From Russia, with Love is the fifth novel by the English author Ian Fleming to feature his fictional British Secret Service agent James Bond. Fleming wrote the story in early 1956 at his Goldeneye estate in Jamaica; at the time he thought it might be his final Bond book. The story centres on a plot by SMERSH, the Soviet counter-intelligence agency, to assassinate Bond in such a way as to discredit both him and his organisation. As bait, the Russians use a beautiful cipher clerk and the Spektor, a Soviet decoding machine. Much of the action takes place in Istanbul and on the Orient Express (pictured). The book was inspired by Fleming's visit to Turkey on behalf of The Sunday Times to report on an Interpol conference; he returned to Britain by the Orient Express. From Russia, with Love deals with the East–West tensions of the Cold War, and the decline of British power and influence after the Second World ...

The Suns Spectrum with its Missing Colors

Image
It is still not known why the Sun's light is missing some colors. Here are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our white-appearing Sun emits light of nearly every color, it does indeed appear brightest in yellow-green light. The dark patches in the above spectrum arise from gas at or above the Sun's surface absorbing sunlight emitted below. Since different types of gas absorb different colors of light, it is possible to determine what gasses compose the Sun. Helium, for example, was first discovered in 1870 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all. via NASA https://ift.tt/2OQxUWg

The Wikipedia article of the day for September 26, 2018 is U.S. Route 25 in Michigan . US Highway 25 (US 25) was a highway in the state of Michigan that ran northeasterly from the Ohio state line near Toledo through Monroe and Detroit to Port Huron. Continuing near the foot of the Blue Water Bridge, it proceeded north and northwesterly along the Lake Huron shoreline to the tip of The Thumb in Port Austin. Created with the initial US Highway System in 1926, US 25 followed some roadways dating from the 19th and early 20th centuries, and replaced several state highway designations. The highway was extended to Port Austin in 1933. Starting in the early 1960s, segments of Interstate 75 and Interstate 94 were built, and US 25 was shifted to follow them concurrently south of Detroit to Port Huron. On September 26, 1973, the entire designation was removed from the state. The final routing of the highway is still maintained by the state under eight different desig...

What can you see in the night sky this season? The featured graphic gives a few highlights for Earth's northern hemisphere. Viewed as a clock face centered at the bottom, early (northern) autumn sky events fan out toward the left, while late autumn events are projected toward the right. Objects relatively close to Earth are illustrated, in general, as nearer to the cartoon figure with the telescope at the bottom center -- although almost everything pictured can be seen without a telescope. As happens during any season, constellations appear the same year to year, and, as usual, the Leonids meteor shower will peak in mid-November. Also as usual, the International Space Station (ISS) can be seen, at times, as a bright spot drifting across the sky after sunset. Planets visible after sunset this autumn include Jupiter and Mars, and during late autumn, Saturn. via NASA https://ift.tt/2QUpFK9

The Wikipedia article of the day for September 25, 2018 is Æthelbald of Mercia . Æthelbald was the King of Mercia in what is now the English Midlands from 716 until he was killed in 757. He came to the throne after the death of his cousin, King Ceolred, who had driven him into exile. During his long reign, Mercia became the dominant kingdom of the Anglo-Saxons, and recovered the position of pre-eminence it had enjoyed during the strong reigns of Mercian kings Penda and Wulfhere between about 628 and 675. When Æthelbald came to the throne, both Wessex and Kent were ruled by stronger kings, but within fifteen years Æthelbald was ruling all England south of the river Humber, according to the contemporary chronicler Bede. Æthelbald was killed in 757 by his bodyguards. He was succeeded briefly by Beornred, of whom little is known. Within a year, Offa, the grandson of Æthelbald's cousin Eanwulf, had seized the throne, possibly after a brief civil war. Under Offa, Mercia entered its mos...

Rover 1A Hops on Asteroid Ryugu

Image
Two small robots have begun hopping around the surface of asteroid Ryugu. The rovers, each the size of a small frying pan, move around the low gravity of kilometer-sized 162173 Ryugu by hopping, staying aloft for about 15 minutes and typically landing again several meters away. On Saturday, Rover 1A returned an early picture of its new home world, on the left, during one of its first hops. On Friday, lander MINERVA-II-1 detached from its mothership Hayabusa2, dropped Rovers 1A and 1B, and then landed on Ryugu. Studying Ryugu could tell humanity not only about Ryugu's surface and interior, but about what materials were available in the early Solar System for the development of life. Two more hopping rovers are planned for release, and Hayabusa2 itself is scheduled to collect a surface sample from Ryugu and return it to Earth for detailed analysis before 2021. via NASA https://ift.tt/2NybBIq

The Wikipedia article of the day for September 24, 2018 is Operation Ke . Operation Ke was the largely successful withdrawal of Japanese forces from Guadalcanal in the Solomon Islands during World War II. All attempts by the Japanese army to recapture Henderson Field, the only airfield on the island being used by Allied aircraft, had been repulsed with heavy losses. Japanese ground forces had been reduced from 36,000 to 11,000 through starvation, disease, and battle casualties. Attempting to reinforce and resupply the ground forces on the island, Japanese naval forces were also suffering heavy losses of troops and matériel, including a submarine sunk in late January (wreckage pictured). The main withdrawal was carried out on the nights of 1, 4, and 7 February by destroyers. The Japanese evacuated 10,652 men from Guadalcanal, of whom 600 died during the withdrawal. On 9 February, Allied forces realized that the Japanese were gone and declared Guadalcanal secure, ending the six-month c...

Equinox: Analemma over the Callanish Stones

Image
Does the Sun return to the same spot on the sky every day at the same time? No. A more visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured analemma was composed from images taken every few days at 4 pm near the village of Callanish in the Outer Hebrides in Scotland, UK. In the foreground are the Callanish Stones, a stone circle built around 2700 BC during humanity's Bronze Age. It is not known if the placement of the Callanish Stones has or had astronomical significance. The ultimate causes for the figure-8 shape of this an all analemmas are the tilt of the Earth axis and the ellipticity of the Earth's orbit around the Sun. At the solstices, the Sun will appear at the top or bottom of an analemma. Equinoxes, however, correspond to analemma middle points -- not the intersection point. Today at 1:54 am (UT) is the equinox ("equal night"), when day and night are equal over all...

The Wikipedia article of the day for September 23, 2018 is Red-billed tropicbird . The red-billed tropicbird is a seabird, one of three species in the family Phaethontidae. Resembling a tern, it has mostly white plumage with some black markings on the wings and back, a black mask and a red bill. Most adults have tail streamers that are about two times their body length, and generally longer in males than in females. Described by Carl Linnaeus in his 10th edition of Systema Naturae (1758), this species ranges across the Indian Ocean, the tropical Atlantic, and the eastern Pacific. Nesting takes place in loose colonies. A single egg is laid, and incubated by both sexes for about six weeks. After a chick fledges, the parents will usually stop visiting the nest and the chick will leave. Red-billed tropicbirds of all ages feed on fish and squid, catching them by diving from the air into the water. The birds sometimes follow surface-feeding predators that drive prey to the surface, where t...

Window Seat over Hudson Bay

Image
On the August 18 night flight from San Francisco to Zurich, a window seat offered this tantalizing view when curtains of light draped a colorful glow across the sky over Hudson Bay. Constructed by digitally stacking six short exposures made with a hand held camera, the scene records the shimmering aurora borealis or northern lights just as the approaching high altitude sunrise illuminated the northeastern horizon. It also caught the flash of a Perseid meteor streaking beneath the handle stars of the Big Dipper of the north. A few days past the meteor shower's peak, its trail still points across the sky toward Perseus. Beautiful aurorae and shower meteors both occur in Earth's upper atmosphere at altitudes of 100 kilometers or so, far above commercial airline fights. The aurora are caused by energetic charged particles from the magnetosphere, while meteors are trails of comet dust. via NASA https://ift.tt/2I5sIeB

The Wikipedia article of the day for September 22, 2018 is Guy Burgess . Guy Burgess (1911–1963) was a British diplomat and Soviet agent, a member of the Cambridge Five spy ring that operated from the mid-1930s to the early years of the Cold War. His defection in 1951 to the Soviet Union, with his fellow-spy Donald Maclean, led to a serious breach in Anglo-American intelligence co-operation, and caused long-lasting demoralisation in Britain's foreign and diplomatic services.

Irregular Galaxy NGC 55

Image
Irregular galaxy NGC 55 is thought to be similar to the Large Magellanic Cloud (LMC). But while the LMC is about 180,000 light-years away and is a well known satellite of our own Milky Way Galaxy, NGC 55 is more like 6 million light-years distant and is a member of the Sculptor Galaxy Group. Classified as an irregular galaxy, in deep exposures the LMC itself resembles a barred disk galaxy. Spanning about 50,000 light-years, NGC 55 is seen nearly edge-on though, presenting a flattened, narrow profile in contrast with our face-on view of the LMC. Just as large star forming regions create emission nebulae in the LMC, NGC 55 is also seen to be producing new stars. This highly detailed galaxy portrait highlights a bright core crossed with dust clouds, telltale pinkish star forming regions, and young blue star clusters in NGC 55. via NASA https://ift.tt/2ptuZYh
