Geekwire 8 Jan 2019, 03:11 UTC Less than a year after NASA’s TESS spacecraft was launched, the scientists behind the mission have unveiled their third confirmed planet, a weird alien world that’s between Earth and Neptune in size. And hundreds of additional potential finds are in the pipeline.
Science Blog from SDSS III 7 Jan 2019, 20:45 UTC The SDSS-IV MaNGA survey is providing the most comprehensive census of the stellar and ionized gas content of local galaxies to date, but there is another major component of galaxies the SDSS telescope does not see: the cold gas. Cold gas plays the key role of fueling the formation of new stars. Galaxies with ongoing star formation tend to have lots of cold gas, while those with no ongoing star formation have very little cold gas. Figuring out how and why galaxies acquire, consume, and/or lose their gas over time is fundamentally important to our understanding of galaxy evolution as a whole.
Geekwire 7 Jan 2019, 18:10 UTC The cigar-shaped object known as ‘Oumuamua may be the first interstellar interloper to be discovered, but it’s not likely to be the last. Statistics suggest that there are lots more space rocks like it out there.
Bad Astronomy 7 Jan 2019, 14:00 UTC When you look at the full Moon through binoculars or a small telescope, one of the most prominent features on the surface is the crater Tycho. It's an impact feature about 86 kilometers wide, situated near the southern edge of the Moon's near side. It's relatively young — maybe 100 million years old — and fresh craters tend to be brighter, making it easy to spot. But that's not why it's so prominent: It's the rays, the collection of long, bright features pointing radially away from the crater. Tycho sports rays hundreds of kilometers long, some over a thousand.

Universe Today 6 Jan 2019, 19:50 UTC This year, SpaceX will test out a miniaturized version of its super-heavy launch vehicle, which is known as the Starship (aka. the Big Falcon Rocket). This test launch will validate the design of the rocket and how it fairs at supersonic speeds and deals with the cryogenic environment of space. It will also serve as an opportunity to conduct the delivery of the next batch of SpaceX’s Starlink satellites.
