#CitizenScience afficionados, #Euclid scientists would like to again solicit your input for classifying #GravitationalLensing systems. We need a sprint finish before the science analysis can be completed. 18000 galaxies that are maybe acting as lenses are waiting for your eyes and brains. 🔭 #ESA

“Hubble and Webb are like looking through a keyhole at an individual object,” says Kristen McQuinn, who heads the Nancy Grace Roman Space Telescope mission office at the Space Telescope Science Institute in Baltimore. “With Roman, it’s like opening the door, and now you see everything." 🔭 #NASARoman

How Roman will unlock the universe

This next-generation space telescope will blow past its predecessors to answer questions about everything from stars and planets to dark matter and dark energy.

Hopefully today you caught wind of the exciting possible dark matter detection at the LZ experiment. But what’s dark matter again? What’s LZ? What does all of this mean??? 1/10 ⚛️🧪

In Spain for the 12 August Total Solar Eclipse? ☀️ Come watch it with us in León. Join scientists, engineers and astronomy experts for a free programme of: 🔴 interactive activities 🔴 talks and 🔴 live observations. 🔭 🧪 1/3 #EuropeanSolarEclipse

An infographic showing where the 12 August 2026 total solar eclipse will pass over Spain. On the right, there is a large map of the Iberian Peninsula, with a shaded band cutting diagonally across it from the northwest to the northeast. On the upper left, the Canary Islands are shown, with lines showing the maximum percentage of darkness during the eclipse. On the lower left, shape of the Moon's shadow is shown on the Iberian Peninsula at 20:27, 20:29, 20:31 and 20:32 CEST.

Webb & Hubble have looked at thousands of young star clusters in four nearby galaxies ✨🧪🔭 Their new findings give us a better grasp of star formation and how planets form. Read more 👉 www.esa.int/Science_Expl... @science.esa.int

This image shows the four galaxies studied in this research, each of which has previously been the subject of a Picture of the Month: Messier 51 (top left), Messier 83 (top right), NGC 4449 (bottom left), and NGC 628 (bottom right).

After a ten-day mission around the moon, the Artemis II astronauts will have traveled nearly 700,000 miles. Today is the final hurdle: reentry. Here's where we stand right now: www.scientificamerican.com/article/nasa...

A graphic of the Artemis II reentry timeline. The process takes 13 minutes for the capsule to travel from 400,000 feet above Earth down to the ocean. Also marked are a communications blackout spanning from about 30 seconds to 6 minutes into the process and the parachute deploy from 10 to 12.5 minutes.

📸 This new NASA/ESA #Hubble Space Telescope image features the Cat’s Eye Nebula (NGC 6543). Hubble’s sharp vision meets Euclid’s wide view to uncover this spectacular portrait of a dying star. esahubble.org/images/potm2... @science.esa.int @stsci.edu

Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.

Hello Bluesky 👋🏻 I've been lurking around for a few months now, but figured it's finally time for a proper intro. So: hi, I'm Alex! I'm a researcher in astrophysics, and I specialize in galaxy hunting 🌌 Outside of that, you'll typically find me running or baking (usually one after the other).
