Space Station Threshold

From a University of Wisconsin press release: Though still under construction, the IceCube Neutrino Observatory at the South Pole is already delivering scientific results — including an early finding about a phenomenon the telescope was not even designed to study. IceCube captures signals of notoriously elusive but scientifically fascinating ...

Massive stars live fast and die young. But they are also beautiful. This amazingly spectacular new image from ESO shows the brilliant and unusual star Wolf-Rayet 22 nestled within billowing, colorful folds of the Carina Nebula. WR 22 is one of many exceptionally hot and brilliant stars contained by the beautiful Carina Nebula (also known [...]

Often, writing about astronomy tends to mirror the job of those writing for the Guiness Book of World Records – just when you think a record is practically unbeatable, somebody else appears to show up the previous record-holder. This is surely the case with the stellar heavyweight (er, "heavymass") R 136a1, which has been shown ...

If you take a lot of digital pictures, you're probably familiar with the frustration of keeping track of dozens of files, and always running out of hard drive space to store them. Well, the scientists and engineers on NASA's Wide-field Infrared Survey Explorer (WISE) mission have no pity for you. Their spacecraft just finished ...

I feel a certain empathy for brown dwarfs. The first confirmed finding of one was only fifteen years ago and they remain frequently overlooked in most significant astronomical surveys. I mean OK, they can only (stifles laughter) burn deuterium but that's something, isn't it?(...)Read the rest of Astronomy Without A Telescope – ...

Greetings, fellow SkyWatchers! Are you ready for a rock the night weekend? Then come along as you won't need a telescope to watch the movement of the planets and the Perseid meteor shower heating up your evenings! If you'd still like a challenge, then why not chase bright asteroid Ceres with binoculars – or look [...]

How do massive stars form? This has been one of the more hotly debated questions in astronomy. Do big stars form by accretion like low-mass stars or do they form through the merging of low mass protostars? Since massive stars tend to be quite far away and usually are surrounded by a shroud of dust, [...]

What a gorgeous new Hubble image! At first glance this object looks like a beautiful, giant, translucent bird. But it is actually star shedding its outer atmosphere. The cloud around this bright star is called IRAS 19475+3119. It lies in the constellation of Cygnus (the Swan) about 15, 000 light-years from Earth in the plane [...]

According to AAVSO Special Notice #212: "Hiroshi Matsuyama (MTH), Kanimbla, Queensland, Australia, reports and Rod Stubbings (SRX), Tetoora Road, Victoria, Australia, confirms that the SU UMa-type dwarf nova QZ Vir (formerly called T Leo) is in outburst, and possibly in superoutburst." (...)Read the rest of Bright Outburst of QZ Virginis ...

It's possible that if we do eventually observe the hypothetical objects that make up the hypothetical Oort cloud, they will all be a deep red color. This red coloring will probably be a mix of ices, richly laced with organic compounds – and may represent remnants of the primordial material from which the solar system [...]
