Explosion on Jupiter Spotted by Amateur Astronomers George Hall
I am awaiting images of the impact scar, but if you have a large enough telescope and a clear sky, be careful not to mistake the barges which appear on the NEB as a possible impact scar. The impact scar should appear on the equator-ward edge of the NEB, which is also where the barges are. Barges are caused by upwellings from Jupiter’s lower atmosphere, and can sometimes be dark enough to be mistaken for shadows cast by Jupiter’s Galilean moons.
Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant the nebula is understandably not the only cosmic cloud to evoke the imagery of flowers. The complex and beautiful nebula is shown here in a composite image that maps emission from ionized sulfur, hydrogen, and oxygen atoms into red, green, and blue colors. Ultraviolet radiation from young, energetic O star HDE 227018 ionizes the atoms and powers the emission from the Tulip Nebula. HDE 227018 is the bright star very near the blue arc at image center.
This is a recent true color image taken by Nasa and the Japanese Space Agency showing Venus in transit around our sun.
Echoing the arc of the Milky Way (center), a meteor—or possibly a satellite reflecting the sun’s rays—streaks earthward near Cagnes-sur-mer in southeastern France in a picture submitted May 17 by National Geographic Your Shot user Jerome Cassou.
Meteors are mostly sand grain-size particles that enter Earth’s atmosphere at high speed, burning up and superheating the air around them, which creates the characteristic short-lived streaks of light.
Outfitted in a homemade spacesuit, “Camilla” the rubber chicken rides into the stratosphere on March 3 as part of an experiment to measure solar radiation at point-blank range.
Students with Bishop Union High School in California launched the chicken—the mascot of NASA’s Solar Dynamics Observatory—before and during a solar storm. For both flights Camilla wore a pair of radiation badges of the same kind used by medical technicians and nuclear workers to assess dosages.
The results will help the students design a future astrobiology project to test whether certain species of microbes can survive the harsh conditions at the edge of space.

Venus to Appear in Once-In-A-Lifetime Event |
On 5 and 6 June this year, millions of people around the world will be able to see Venus pass across the face of the Sun in what will be a once-in-a-lifetime experience.
It will take Venus about six hours to complete its transit, appearing as a small black dot on the Sun’s surface, in an event that will not happen again until 2117.
In this month’s Physics World, Jay M Pasachoff, an astronomer at Williams College, Massachusetts, explores the science behind Venus’s transit and gives an account of its fascinating history.
Transits of Venus occur only on the very rare occasions when Venus and Earth are in a line with the Sun. At other times Venus passes below or above the Sun because the two orbits are at a slight angle to each other. Transits occur in pairs separated by eight years, with the gap between pairs of transits alternating between 105.5 and 121.5 years — the last transit was in 2004.
Building on the original theories of Nicolaus Copernicus from 1543, scientists were able to predict and record the transits of both Mercury and Venus in the centuries that followed.
Johannes Kepler successfully predicted that both planets would transit the Sun in 1631, part of which was verified with Mercury’s transit of that year. But the first transit of Venus to actually be viewed was in 1639 — an event that had been predicted by the English astronomer Jeremiah Horrocks. He observed the transit in the village of Much Hoole in Lancashire — the only other person to see it being his correspondent, William Crabtree, in Manchester. continue reading
Hey, I'm Ryan, otherwise known as Captain Couch.
I'm into hardcore, hardstyle, and drum and bass, but I'll listen to just about anything electronic. Except for trap.
I'm also into anime and manga and other weeb stuff. But I'm not a weeaboo. I promise.
I've also been a DJ for a few years and I mix stuff. Whoo.
I'm also a computer programmer. Fun stuff.
Feel free to say hi. :)
