Saturn’s moon Titan has some odd similarities to Earth: it has clouds, lakes and rain, except they’re made of methane and ethane.
About 160,000 light-years away, two stars are overlapping in what could be poetically described as an explosive catastrophic kiss.
After five years of painstakingly stitching together pictures of the Milky Way, astronomers from Ruhr University Bochum have finally completed their masterpiece: the largest ever space photo. It has a whooping 46 billion megapixel and 194 GB in file size. It’s so large, in fact, that the astronomers had to cut it in 268 sections for it be manageable.
It’s something no human has ever seen before: as a star reaches its terminal phase, it blows up the system around it.
Hurricane Joaquin is an active tropical cyclone that severely impacted large parts of the Bahamas and is currently threatening Bermuda, although its extremities will also pass through other areas in the Atlantic, including Britain. Now, according to NASA data, the hurricane will be experiencing a phenomenon called eyewall replacement.
A rosy, star-forming nebula thousands of light years away from Earth is “blossoming” in a dazzling cosmic spectacle. Messier 17, also known as the Omega Nebula, the Swan Nebula and the Horseshoe Nebula was shot in some remarkable photos revealed by the European Space Agency.
I know, I know, we’ve spoiled you with awesome photos of Pluto already, this couldn’t possibly surprise you, could it? Well, I dare say NASA has done it again – this new batch of New Horizons images is absolutely breathtaking.
An ocean of magma could explain why Jupiter’s moon Io has volcanoes in the “wrong place”. This would also mean that Io has an ocean of liquid water beneath its surface and might be potentially habitable.
Cryogenic sleep is usually the stuff of science fiction, most recently featured in the award winning blockbuster Interstellar. Of course, the most epic display of cryosleep can be found in Alien, in my humble opinion. Nevertheless, the theme is the same: cosmic voyagers are suspended in a sort of low metabolic state where vital functions are kept to a bear minimum by cooling the body, while not actually killing the person. It’s quite useful, especially when you consider interstellar travel involving years, decades or even perhaps centuries of traveling. It’s no wonder then that NASA is interested in actually turning this into a real-life application.
Hubble has recently captured a dazzling image of a “cosmic butterfly” – the planetary nebula (PN) M2-9. The star has not only ejected its outer layers, but exposed its inner core, which is now illuminating the layers in a spectacular and violent display.
