Direct link NASA’s Mission to Visit 8 Asteroids, Lucy, Launches on October 16th

15 Oct 2021, 14:49 UTC An early morning launch is planned for the Lucy spacecraft, the first space mission to study Jupiter’s Trojan asteroids. Tomorrow, October 16 at 5:34 a.m. EDT is the first day and time in Lucy’s 21-day launch window, and current weather conditions show a 90% chance of favorable conditions for liftoff from Cape Canaveral Space Force Station in Florida. The launch window remains open for 75 minutes.
221180: Earth's solid inner core may be a little bit mushy

Direct link Earth's solid inner core may be a little bit mushy

15 Oct 2021, 13:00 UTC I know that I usually write about stuff you have to look up to see, but I also like to learn about what's going on under my feet. I'm biased; like most of you I live on a planet. So I was fascinated to read that new findings imply that the Earth's inner core may not be entirely solid, and instead might have a mushy layer up to 250 kilometers deep in its upper reaches, and there could be both solid and liquid bits mixed in that layer as well.

15 Oct 2021, 10:31 UTC The last decades of “exoplanet hunting” – the search for planets orbiting stars other than the Sun – have allowed us to better understand the evolutionary paths leading to the current architecture of our planetary system as well as of other discovered systems. To date, the discovery of 4715 exoplanets belonging to 3247 planetary systems has been confirmed, and there are approximately 5900 planets awaiting confirmation.

14 Oct 2021, 13:00 UTC You are made of star stuff. Carl Sagan said this in his series Cosmos, and it’s literally true. We know the early Universe only had hydrogen and helium (and a soupçon of lithium) in it, and all the heavier elements — carbon, oxygen, phosphorus, and more — were made in stars. These were then ejected into space, eventually making their way into you (some steps may have been skipped here for brevity).

Direct link Next Generation Telescopes Could Detect the Direct Collapse of Enormous Black Holes Near the Beginning of Time

13 Oct 2021, 12:57 UTC The first black holes to appear in the universe may have formed from the direct collapse of gas. When they collapsed, they released a flood of radiation, including radio waves. A new study has found that the next generation of massive radio telescopes may be able to detect these bursts, giving precious insights into a critical epoch in the history of the universe.

12 Oct 2021, 11:00 UTC Strange radio signals are coming from the direction of the centre of the galaxy and we aren’t sure what is emitting them. They turn on and off seemingly at random, and their source must be unlike anything else we have seen before.

Direct link JWST’s 30 Days of Terror

11 Oct 2021, 14:45 UTC It’s been a long and winding road getting the James Webb Space Telescope from concept to reality. And finally, after decades of planning, work, delays, and cost overruns, the next generation of space telescopes is finally ready to launch. But even now, as the telescope might be secretly traveling by cargo ship to the European Space Agency (ESA) launch site in French Guiana, everyone involved with the JWST project knows a successful launch isn’t the final victory.

Direct link Gravitational-Wave Observatories Should be Able to Detect Primordial Black Hole Mergers, if They’re out There

11 Oct 2021, 12:52 UTC The tumultuous era of the big bang may have been chaotic enough to flood the universe with primordial black holes. Eventually some of those black holes will find each other and merge, sending out ripples of gravitational waves. A comprehensive search for those gravitational wave signatures hasn’t found anything, putting tight constraints on the abundance of these mysterious objects.
