The black hole that ate its own star. This is some neat science!
A new paper reports that VFTS 243, a massive binary system featuring an O-class star and a 10 solar-mass black hole companion, might have formed through the 'complete collapse scenario'.
Here is a 360° panorama captured by Curiosity at her current location, with North at center and South at both ends, on top of two large and small scale maps with her position.
There are many geological features in the panorama, can you find them in the maps?
I taunt astronomers in other EM regimes because unlike us cool radio astro folks, they mostly can't do astronomy during the day (where we can).
Now, folks from our uni (Macquarie Uni) and fellow PhD'er Sarah Caddy, are building telescopes for daytime obs.
THIS IS BETELGEUSE IN THE DAY! 🤯
To get these results, we've built a telescope that has MANY eyes, and named it after the huge spider we have here called 'The Huntsman' (which of course, has many eyes).
Gliese 12 b is an Earth-size planet orbiting in the temperate zone around a nearby, stable red dwarf star. It's a Rosetta Stone world that will tell us a lot about how many superficially earthlike planets actually have the right conditions for life.
If you're the kind of person who likes to go deep, I got you.
The full research paper is freely available online, providing the technical details of how astronomers found the Earth-size planet Gliese 12b, and what we really do (and do not) know about it.
Are there major initiatives for which the capabilities of @ChandraScience are absolutely required to address fundamental questions about our current understanding of the Universe that would represent a crucial missed opportunity if they are not completed during Chandra's lifetime?
The community responded, and we are pleased to announce two Chandra Legacy Programs https://cxc.harvard.edu/CLP/
Non-thermal energy components evolving from z=4 to z=0 in the last of my #SimulatedUniverses
The combination of all these, for the case of relativistic electrons, gives the total synchrotron emission from the cosmic web, from galaxies to filaments.
Did you ever want to download a AAS Research Note (https://iopscience.iop.org/journal/2515-5172) as a PDF. That feature is now available according to @Chrislintott the feature is now available. yay! "It's hidden under the 'Article and Author information' tab, but it's there! " #astrodon
ESA's Euclid space telescope is designed to map dark matter and dark energy across the universe. But as it is getting started, Euclid is also sending back gorgeous cosmic snapshots.
Finally, after months of work, the #ESAEuclid Early Release Observation images, data, first science results, and #Euclid mission reference papers have been released. You can read more in our blog post, which has links to the papers, the press releases, and everything else:
It is annoying in #mastodon to still keep missing a lot of interesting posts by people in my list, which live in an almost specular time zone. although I have put them in dedicated lists, if I forget to check them regularly, their stuff is just lost to me.
So the only thing is to click on the 🔔 for each of such profiles. That however messes up with the notifications.
ffff....
Why can't early black holes not grow by eating dark matter? No radiative pushback, but perhaps too small a cross-section? Would that depend on DM temperature and particle mass, but already excluded by candidate parameters?
I thought I was trained in this #astro business, but... 🤷🏼♂️ #Astrodon
For the first time since Nov. 2023, two of the four instruments aboard the Voyager 1 spacecraft (currently ~24,472,559,000 km away or about 22.5 light hours from us) have started re-transmitting science data!
These spacecraft are older than me and still going strong.
The summer 2024 NASA's Astrophoto Challenge is now open! This summer's target: Cassiopeia A.
Make your own images with real NASA data using a simple, online tool. Then, submit your image. Standout entries are featured on the website and get comments from expert judges.
The LSST Camera is at the summit. Construction of the Vera C. Rubin Observatory is on the path to completion - The camera was the last major piece of equipment/component - still lots to do, but we're getting closer to the start of commissioning and operations with Rubin Observatory and LSSTCam! Well done to all the @VRubinObs construction project and observatory staff and collaborators who made this milestone happen! https://rubinobservatory.org/news/camera-arrives-chile#astrodon
