NASA’s Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago. This is a Hubble Space Telescope view of supernova SN UDS10Wil, nicknamed SN Wilson that exploded over 10 [continue reading]
Astronomers detect titanium oxide and titanium dioxide around the giant star VY Canis Majoris An international team of astronomers, including researchers from the Max Planck Institute for Radio Astronomy and from the University of Cologne, successfully identified two titanium oxides in the extended atmosphere around a giant star. The object VY Canis Major is [continue reading]
The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns’ worth of gas in an eruption that made it the second-brightest star after Sirius. That was just a precursor to the main event, since it will eventually go supernova. Eta Carinae, situated about 8000 light-years away [continue reading]

Evans (University of Virginia, Charlottesville/NRAO/Stony Brook University) Arp 299, consisting of IC 694 (left) and NGC 3690 (right), is an interacting pair of barred irregular galaxies that lie about 134 million light-years away in [continue reading]
Particle Decay ‘Smoking Gun’ Settles Long Debate
Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in this new image from ESA’s Herschel space observatory. The star and its arc-shaped shields could collide with an intriguing dusty ‘wall’ in 5000 years. Composite color image of Betelgeuse. North is to the top left, east is to the bottom left, and [continue reading]
