Direct link No supernova for you: Betelgeuse is brightening again right on schedule

24 Feb 2020, 14:00 UTC Maybe you'll be relieved, or maybe you'll be upset you missed out, but it really looks like Betelgeuse has turned a corner and is getting brighter again.

21 Feb 2020, 15:01 UTC It really is the ‘glue’ that holds the Universe together, enabling structures like our own galaxy to form in the first place.

Direct link What Snuffed Out Star Formation in This “Monster” Galaxy?

21 Feb 2020, 13:14 UTC Within the first several billion years of the universe, galaxies were growing like the newborns they were — turning gas into stars, sometimes at fantastic rates. But astronomers have discovered one massive galaxy that has apparently stopped forming stars altogether.

21 Feb 2020, 13:12 UTC Sending a mission to moons of Mars has been on the wish list for mission planners and space enthusiasts for quite some time. For the past few years, however, a team of Japanese Space Agency (JAXA) engineers and scientists have been working on putting such a mission together.

Direct link New Horizons May Have Solved Planet Formation Cold Case

20 Feb 2020, 14:22 UTC Not that long ago, it seemed the glory days of NASA’s New Horizons mission were in the rearview mirror, left behind with its historic Pluto encounter in 2015. Then, early last year, the spacecraft streaked by Arrokoth, a bit of flotsam drifting through the Kuiper Belt—the diffuse ring of primitive icy bodies beyond Neptune, of which Pluto is the largest member.

20 Feb 2020, 14:19 UTC Astronomers are finding new exoplanets nearly every day. But this particular answer probably won’t change.

19 Feb 2020, 15:32 UTC With the February dark of the Moon upon us, we have a fine opportunity to enjoy some winter sights. Perhaps most appealing for naked-eye observers is an impressive collection of stellar luminaries. Face south at nightfall, and no fewer than seven stars of first magnitude or brighter can be taken in with a single view. Most are included in the Winter Hexagon, as shown in the chart above.

Direct link An Earth-sized planet may be igniting an aurora around a nearby red dwarf star

19 Feb 2020, 14:00 UTC A team of astronomers has just announced they may have found a planet orbiting the red dwarf star GJ 1151, but the technique is entirely novel: The planet is interacting with the star magnetically, creating an aurora not on the planet but on the star itself!

Direct link A New Look at the ‘Pale Blue Dot’

18 Feb 2020, 17:25 UTC The 30th anniversary of the famous ‘Pale Blue Dot’ image of Earth, which took place on February 14, is an appropriate occasion for the newly updated image below, which brings the latest methods to bear on the data Voyager 1 presented us. Our planet takes up less than a single pixel and for that reason is not fully resolved. The rays of sunlight due to scattering within the camera optics intersect with Earth, reminding us that from Voyager’s position 6 billion kilometers from home, the Earth/Sun separation was only a matter of a few degrees.
