Two years ago as the Cassini probe made its daring final plunge into the atmosphere of Saturn, it flew past for a closer look at a few of the gas giant’s inner moons. Now a NASA team has analyzed the data and uncovered some intriguing new details about these tiny worlds, including how they’re busily scooping up material from Saturn’s rings and growing into weird shapes.
NASA has released images from the Hubble Space Telescope showing an asteroid that is tearing itself apart. Located 214 million mi (344 million km) from the Sun, the 2.5-mile-wide (4-km) asteroid (6478) Gault is spinning so fast that it is self-destructing and throwing off debris tails half a million miles (800,000 km) long.
In June 2018, a bright light burst into the skies over the Northern Hemisphere. At a glance it looked like any other supernova, but on closer inspection this thing turned out to be far weirder. Officially known as AT2018cow (but quickly nicknamed “The Cow”), astronomers now believe the ATLAS survey’s twin telescopes in Hawaii captured an unprecedented look at the birth of a black hole or a neutron star.
from the Daily Mail:
A Chinese rover is making its tracks on the soft surface of the ‘dark’ side of the moon after touching down on our nearest celestial neighbour.
The Yutu-2 – or Jade Rabbit 2 – rover drove off its lander’s ramp and onto the exterior of the moon’s far side at 10:22pm Beijing time (2:22 pm GMT) on Thursday, about 12 hours after the Chinese spacecraft carrying it came to rest.
China’s space agency later posted a photos online, revealing lunar rover several yards away from the spacecraft.
When we think of celestial threats to our planet, we usually think of big asteroids and comets, and maybe the odd gamma ray burst or supernova. What we probably wouldn’t think of is an entire galaxy bearing down on us, but according to a new study, that’s exactly what’s happening right now. The Large Magellanic Cloud (LMC), a nearby dwarf galaxy, is on a collision course with the Milky Way, but there’s no need to worry just yet – the starry smashup won’t begin for another two billion years or so.
