The image offers a stunning variety of objects — from bright stars ranging from blue to red in color, to nearby blue spiral galaxies, to distant red galaxy groups — demonstrating the broad range of science made possible by Rubin data ✨🔭🧪

Only Rubin can produce an image this large and full this quickly!🔭🧪
And by full, we mean FULL. Apart from a few foreground stars in our own Milky Way, this image contains about 10 million galaxies.

The Virgo Cluster is about 55 million light-years away from Earth, and is the nearest large collection of galaxies to our own Milky Way.🔭🧪
Rubin captured this stunning image in "survey mode" using the 3200-megapixel LSST Camera.

In addition to these never-before-seen cosmic neighbors, Rubin detected another ~1800 previously-known asteroids, bringing the total detections to just under 4000 in just 10.5 hours!🔭🧪
In other words, over half of Rubin's first detections are new discoveries☄️

This is the first time an image has ever been snapped of an exoplanet in such a misaligned system. (6/6) 🔭 🧪

Webb’s image of 14 Herculis c also provides insights into a planetary system unlike most others studied in detail with Webb. The central star, 14 Herculis, is similar in age and temperature to our own Sun, but a little less massive and cooler. (5/6)

“The colder an exoplanet, the harder it is to image, so this is a totally new regime of study that Webb has unlocked with its extreme sensitivity in the infrared,” said William Balmer, co-first author of the new paper and graduate student at Johns Hopkins University. (4/6)

The new data suggests 14 Herculis c, which weighs about 7 times the planet Jupiter, is as cool as 26 degrees Fahrenheit (minus 3 degrees Celsius). (3/6)

The exoplanet, 14 Herculis c, is one of the coldest imaged to date. While there are nearly 6,000 exoplanets that have been discovered, only a small number of those have been directly imaged, most of those being very hot (hundreds or even thousands of degrees Fahrenheit). (2/6)

The four moons in this study — Ariel, Umbriel, Titania, and Oberon — are tidally locked to Uranus, so that they always show the same side to the planet. (5/5) #AAS246 🔭 🧪

Instead, they found no evidence for darkening on the moons’ trailing sides, and clear evidence for darkening of the leading sides of the outer moons. This indicates that Uranus’ magnetosphere might not interact much with its large moons, contradicting existing data. (4/5)

This would be due to radiation darkening of their trailing sides by charged particles such as electrons trapped in Uranus’ magnetosphere. (3/5)

The team predicted that, based on interactions with Uranus' magnetosphere, the “leading” sides of these tidally locked moons, which always face in the same direction in which they are orbiting the planet, would be brighter than the “trailing” sides, always facing away. (2/5)

In most of the other cases, the galaxies don't even come close enough for dynamical friction to work effectively. In this case, the two galaxies can continue their orbital waltz for a very long time. (7/7) 🔭 🧪

The effects of the orbits of Andromeda’s satellite galaxy, M33, and a satellite galaxy of the Milky Way—the Large Magellanic Cloud—were considered. In half of the simulations, the two main galaxies fly past each other separated by around half a million light-years or less. (6/7)

Astronomers considered 22 different variables that could affect the potential collision between our galaxy and our neighbor, and ran 100,000 simulations stretching to 10 billion years into the future. (5/7)
