"The paper is likely to be greeted with heavy scepticism, but with the influential DESI consortium independently reaching a similar conclusion earlier this year, a fierce debate is opening up in cosmology over the nature of dark energy and the probable fate of the universe."

Is It Time For A New Model Of The Universe?
Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

🔭 Virgo Cluster Galaxies

Image Credit & Copyright: Daniel Adibi

apod.nasa.gov/apod/ap25041...
Galaxies of the Virgo Cluster are scattered across this nearly 4 degree wide telescopic field of view. About 50 million light-years distant, the Virgo Cluster is the closest large galaxy cluster to our own local galaxy group. Prominent here are Virgo's bright elliptical galaxies from the Messier catalog, M87 at bottom left, and M86 and M84 near center right. M86 and M84 are recognized as part of Markarian's Chain, the visually striking line-up of galaxies on the that runs through the upper portion of this frame. Near the middle of the chain lies an intriguing interacting pair of galaxies, NGC 4438 and NGC 4435, known to some as Markarian's Eyes. Still, giant elliptical galaxy M87 dominates the Virgo cluster. It's the home of a super massive black hole, the first black hole ever imaged by planet Earth's Event Horizon Telescope.

The scientific return of the @vrubinobs.bsky.social is going be out of this world! Ba dum tss!

Over the course of its decade-long survey, Rubin will capture every part of the Southern sky ~1000 times, in more detail than has been possible before — creating the greatest cosmic movie ever made. 🔭🧪

Studying billions of objects at once is so fetch! ...okay, we'll stop trying to make fetch happen.

The NSF–DOE Rubin Observatory will image billions of stars and galaxies across the entire Southern sky, night after night, because it's what's called a “survey telescope”—but what does that mean? 🔭🧪

K2-18b is back in the news, now with a bold claim that biosignature molecules (DMS and/or DMDS) have been 'detected at 3σ'.

Most exoplanet astronomers are extremely sceptical about these claims, let's see why (1/n).

On 10 April 2019, the Event Horizon Telescope (EHT) team released the first-ever image of a black hole and its shadow, using radio observations of the heart of M87, a massive galaxy in the Virgo galaxy cluster

Press Release (2019) ➡️ eventhorizontelescope.org/press-releas...

🔭 🧪 #cosmology
Image of a black hole showing a bright, orange-yellow ring-like structure surrounding a dark central region. This ring represents the accretion disk of matter attracted by the black hole, while the dark area in the center is the shadow of the black hole itself, located at the heart of the galaxy Messier 87 (M87). This is the first direct image of a black hole ever captured, made by the Event Horizon Telescope project.
