UGC 1810: Wildly Interacting Galaxy from Hubble
9.05.2017
What's happening to this spiral galaxy? Although details remain uncertain, it surely has to do with an ongoing battle with its smaller galactic neighbor. The featured galaxy is labelled UGC 1810 by itself, but together with its collisional partner is known as Arp 273.
Big Dipper Above and Below Chilean Volcanoes
8.05.2017
Do you see it? This common question frequently precedes the rediscovery of one of the most commonly recognized configurations of stars on the northern sky: the Big Dipper. This grouping of stars is one of the few things that has likely been seen, and will be seen, by every generation.
Ancient Ogunquit Beach on Mars
7.05.2017
This was once a beach -- on ancient Mars. The featured 360-degree panorama, horizontally compressed, was taken by the robotic Curiosity rover currently exploring the red planet. Named Ogunquit Beach after its terrestrial counterpart, evidence...
Star Formation in the Tadpole Nebula
6.05.2017
What's all of the commotion in the Tadpole nebula? Star formation. Dusty emission in the Tadpole nebula, IC 410, lies about 12,000 light-years away in the northern constellation of the Charioteer (Auriga).
Galaxy Cluster Abell 370 and Beyond
5.05.2017
Some 4 billion light-years away, massive galaxy cluster Abell 370 only appears to be dominated by two giant elliptical galaxies and infested with faint arcs in this sharp Hubble Space Telescope snapshot. The fainter...
The Bull s Eye and the Young Moon
4.05.2017
Aldebaran, eye of Taurus the Bull, and a young crescent Moon shared an early evening sky last Friday. The lovely celestial pairing could be enjoyed around planet Earth, but from some locations the Moon was even seen to pass in front of Aldebaran, a dramatic lunar occultation of the familiar bright star.
The Perseus Cluster Waves
3.05.2017
The cosmic swirl and slosh of giant waves in an enormous reservoir of glowing hot gas are traced in this enhanced X-ray image from the Chandra Observatory. The frame spans over 1 million light-years across the center of the nearby Perseus Galaxy Cluster, some 240 million light-years distant.
NGC 3628: The Hamburger Galaxy
2.05.2017
No, hamburgers are not this big. What is pictured is a sharp telescopic views of a magnificent edge-on spiral galaxy NGC 3628 show a puffy galactic disk divided by dark dust lanes. Of course, this deep galactic portrait puts some astronomers in mind of its popular moniker, The Hamburger Galaxy.
Approach above Sunset
1.05.2017
There it is! The Cygnus supply ship was a welcome sight to the astronauts on the International Space Station just over a week ago. Launched three days before on a United Launch Alliance Atlas...
Cooling Neutron Star
30.04.2017
The bright source near the center is a neutron star, the incredibly dense, collapsed remains of a massive stellar core. Surrounding it is supernova remnant Cassiopeia A (Cas A), a comfortable 11,000 light-years away. Light from the Cas A supernova, the death explosion of a massive star, first reached Earth about 350 years ago.
