Our AURA partner, Cerro Tololo is a complex of telescopes and instruments in Chile, at an altitude of 2,200 meters (7,200 feet), and is part of NOIRLab. At right is the Carina Nebula, as observed by Cerro Tololo: https://noirlab.edu/public/programs/ctio/… #AURAPartners

An image of the Carina Nebula shows large orange-lined clouds filled with blue gas. In the center, where the clouds appear to meet, pink and white colors shine. Behind the clouds is a black background.

Because of Hubble's fast orbit around the Earth, it can capture wandering asteroids through their telltale trails in the Hubble exposures. Asteroids "photobomb" Hubble exposures by appearing as unmistakable, curved trails in Hubble photographs. (6/6)

Cataloging asteroids is tricky because they are faint and they don't stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived Hubble images to snag a largely unseen population of smaller asteroids in their tracks. (1/6)

Astronomers used #Hubble's unique capabilities to identify a largely unseen population of very small asteroids. The treasure hunt required perusing 37,000 Hubble images. The payoff? Finding 1,701 asteroid trails: https://bit.ly/4cYTBio

Hubble examined the central region of galaxy NGC 1313 and found it’s filled with open star clusters—groups of young stars that are loosely bound together by gravity.

These clusters tend to disperse after a few million years. Learn why: https://bit.ly/43a0Tvi

One method for studying exoplanets relies on measuring the changes in brightness as planets pass in front of or behind their host stars. #NASAWebb’s observation of TRAPPIST-1 b showed that it has no notable atmosphere.

The Glowing Eye Nebula, aka NGC 6751, “peers” across the cosmos in the constellation Aquila. Like all planetary nebulas, it was formed when a dying sunlike star ejected its outer gaseous layers and then lit them up: https://bit.ly/3Vzox2a

Have you sashayed into spring like the bright star at the center of this Hubble image?

It is illuminating and sculpting the landscape of dust and gas in this region, dubbed the miniature Orion Nebula.

You’ve likely seen the second image, an up-close view of our sun. It was taken by the Daniel K. Inouye Solar Telescope (seen in the first image), part of the National Solar Observatory—one of our AURA partner centers in Hawaii. Learn more about the telescope: https://nso.edu #AURAPartners

This image of the surface of the Sun appears like a piece of dark yellow paper that was wrinkled up into a ball and then unfolded, laying on a surface. The yellow appears dark, almost orange, where the hundreds of creases would be.

In 2018, Hubble captured this image of the Serpens Nebula, a star-forming region that resembles stormy clouds on a spring day. This reflection nebula is home to a unique feature known as the “Bat Shadow”: https://bit.ly/3IOR4tk

Telescope coronagraphs function like an #eclipse! When the glare from a star—including our sun—is blocked, fainter sources of light are able to be seen. Scientists use this simple light-blocking technique to discover planets orbiting other stars.

Abell 370 was the last of six galaxy clusters imaged in the Frontier Fields project, which used gravitational lensing and Hubble’s ability to create deep field images to see galaxies that would normally be hard to observe.
