One of the great things about having spacecraft in orbit around worlds for so many years is we can actually see things change. More than once we’ve documented a new crater or a change on mars generated through a storm. Here we have is one more fabulous find. Formed at most between September 2016 and February 2019, this new crater on Mars is 22 m across, and in the splatter of material around us, we’re finding amazing color (once we exaggerate everything enough), and in the blue of this image, we may be finding water. It’s not certain, but in a CNN report, Veronica Bray, a HiRISE team member and University of Arizona scientist, said “That has not yet been confirmed, but commonly, when a HiRISE image of a new impact shows a blue area, it is sometimes water ice,”
So, cool! But more data is needed. It looks more and more like water exists widely on Mars, which is good for potential live, including potential humans… assuming we can solve the radiation problem… but that’s a different story for a different day.
Sometimes, amazing things are able to hide right next door. This is the case with Teegarden’s star, a small star only 12.5 light years from earth that was only found in 2003. For the past several years, astronomers have peered at this system searching for planets. Now – they have been found. 2 planets, both slightly larger than our Earth, have been found in this stars habitable zone.
This research, led by University of Göttingen researchers, hints that there may be an entire planetary system, not too different from our own, around this nearby star. And the folks on those planets can see us.
According to Professor Ansgar Reiners, “An inhabitant of the new planets would therefore have the opportunity to view the Earth using the transit method,”
This is the first time we’ve found worlds capable of hosting life capable of looking at us and seeing us the same way we see them.
This purple blob is not bleeding purple to show its Twitch spirit.
This is a map of gas inside a galaxy cluster taken with the Chandra XRay observatory. In this blob, you can see slight patterns of brighter and fainter,
If you have ever stirred creamer into coffee, milk into coffee, or honey into anything hot, you now all these different fluids flow someone differently, This is because of how each liquid flows due to differences in viscosity,
By comparing how this purple blobs looks, go how those kinds of fluids look, they learned gas in clusters flows like honey.
Yeah, that’s weird. Just go with it. The universe is weirder than our imaginations usually can imagine.
And in a final feel good story of the day…
Some of you may have heard that the company that purchased SKy and Telescope Magazine a number of years ago recently went bankrupt, putting the continuation of this 100+ year old magazine at risk.
Well, the American Astronomical Society has stepped forward to save the day, and in a bankruptcy auction, the bought the magazine.
From the press release
The AAS anticipates that S&T’s staff of editors, designers, illustrators, and advertising sales representatives will become AAS employees but will continue to work out of the magazine’s offices in Cambridge, Massachusetts.
So, if you thought about letting your subscription lapse – don’t . Things are just looking better as the magazine joins the non-profit world.
