In the constellation Canes Venatici, there are two distorted spiral galaxies with an edge-on view, called Whale galaxy (NGC 4631) and Hockey stick galaxy (NGC 4656). At 25 million light years away, these interacting galaxies are part of the Virgo supercluster. 🔭🧪

In the coming days, teams will transport the Nancy Grace Roman Space Telescope—encapsulated in Falcon Heavy’s fairing—to SpaceX’s hangar at pad 39A, where technicians will attach it to the rocket before sending it out to the launch pad. #NASARoman 🔭 🧪

Test case is the short-period super-Earth GJ 1132 b. The two atmospheres are distinct enough for JWST to tell apart. 🔭
The first image shows the melting curves themselves: reduced in blue melts hotter, oxidised in pink melts cooler.

🔭 Ceci n'est pas notre soleil, mais bien une image de la surface d'une autre étoile 🤯 En l'occurrence, la supergéante rouge Betelgeuse, qui se situe à ~560 a.l. de nous, ici observée dans le domaine des micro-ondes. On y découvre une surface très hétérogène et granuleuse 🤩

Cosmicflows-4 and the Cosmological Consistency of Large-Scale Motions
We study coherent flows in Cosmicflows-4 (CF4) and its constituent catalogs. We fit monopole and dipole moments in nonoverlapping radial bins using a log-distance radial-velocity estimator. For each s...

In one of my picture of the eclipse, taken a little bit before sunset I have a spot on the Moon. It is probably an artefact but there is a slight chance that it is the flash of a meteorite smashing the moon. May I ask you to check your pictures for a similar spot around 18:50 UTC ?

Yet something is puzzling astronomers — and Betelgeuse's close companion star, recently suggested by observations with our VLT, could be behind it.

A bubbling Betelgeuse ⭐️ 🫧
This ALMA image is one of the most detailed views yet of the surface of the iconic star Betelgeuse.
The surface is uneven & lumpy, with peaks and troughs originating from giant bubbles of hot gas rising from deep within the star to its surface.
