ESOcast 3 Nov 2017, 11:00 UTC The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the Sun.

Space Policy Edition #18: Jim Bridenstine vs. the Senate & First Meeting of the National Space Council3 Nov 2017, 05:00 UTC The likely next Administrator of NASA, Jim Bridenstine, appeared before a somewhat skeptical Senate committee to defend his nomination. Casey and Jason recap the hearing and assess Congressman Bridenstine’s chance of moving forward.
ESOcast 2 Nov 2017, 11:00 UTC How can astrophysicists study the story of the Universe? Billions of years ago, when the Big Bang happened, there was no Milky Way Galaxy, no Solar System, no planet Earth and, especially, no human beings to witness these and all the events that followed. So, how would they know about this stuff?
StarDate Online 1 Nov 2017, 06:00 UTC The star Gliese 710 is so faint that it’s invisible to the eye alone. In 1.3 million years, though, it’ll be the brightest star in the night sky, as it passes about a quarter of a light-year away. The encounter could be deadly: The star could deflect some of the icy bodies that surround the Sun, sending them toward the inner solar system, where they could smack into Earth.

The 400 metre wide newly discovered asteroid or comet has been designated A/2017 U1. *Asteroid Itokawa’s violent past Samples of the Asteroid Itokawa indicate the 500 metre wide space rock has had a violent history. The samples were collected by Japan’s Hayabusa spacecraft in 2005. *Rosetta’s comet provides missing link in planet formation Scientists have confirmed that planets are created by small particles of matter coming together over time to form progressively larger and larger bodies. The findings provide an important missing link in sciences understanding of how planets are formed. *Galaxies wobble at the centres of galaxy clusters Existing models on dark matter claim the super dense cores of the largest galaxy clusters contain massive galaxies with so much dark matter that that they never move. However new observations ...
Sky & Telescope 30 Oct 2017, 10:57 UTC As you'll hear in this month's astronomy podcast, Venus and Jupiter are putting on quite a show low in the east before dawn. The return to standard time (November 5th in the U.S. and Canada) means that most of us are still heading home from work as evening’s twilight sets in. but that's a good thing, because it means you can sneak in a little stargazing before dinnertime. Look low in the east before dawn to watch Venus and Jupiter draw closer and closer together. Make sure your horizon is clear in that direction. Sky & Telescope These shorter days also mean it'll likely be dark when you get up, and this month the predawn sky features some drama. Venus has been dazzling the past few months, but now it’s dropping fast. It rises about 90 minutes before sunrise as November opens but only 45 minutes ahead of it at month’s end. Meanwhile, Jupiter is sneaking up from the horizon. As Venus sinks lower down and Jupiter rises up out of the twilight glow, the gap between them shrinks. At their closest they'll be only ¼° apart — but on which date does that happen? Listen to the podcast to ...
