Why is the warm gas-giant exoplanet WASP-107 b so, so puffy? With a moderate temperature and an ultra-low density on par with a microwaved marshmallow, it seems to defy standard theories of planet formation and evolution. (1/7)

How did the warm gas-giant WASP-107 b get to be as big as Jupiter and as puffy as a microwaved marshmallow? Astronomers used #NASAWebb measurements of the planet’s atmosphere to crack the case: https://webbtelescope.pub/44M12FM

Fuzzy caterpillar? Nope! This Hubble image shows a runaway star plowing through a region of dense interstellar gas, creating brilliant structures and trails of glowing gas. The effect is known as a bow shock.

Every six weeks, a maneuver is planned for the James Webb Space Telescope to ensure it stays in its orbit a million miles away. It's carried out by a group of skilled engineers at the Space Telescope Science Institute.

Watch as the team prepares the observatory!

The last facility at AURA we’ll be looking at is the Community Science and Data Center, home to the Astro Data Lab, the science platform with software for astronomy research. It enables the exploration and analysis of large datasets: https://datalab.noirlab.edu

A horizontal image with a black background, showing a map projection of the sky. An oval shows shades of green, blue, yellow and red with a larger concentration of red points in the bottom half. A large swatch of gray is on the upper right of the oval. A red line appears across the oval, starting from the middle left, then dips down in a curve before going up in a curve and ending on the middle right of the oval.

Earlier today, engineers in the Mission Operations Center at STScI performed a regular maneuver to make sure the observatory stays in its orbit at the Second Lagrange Point. It is performed every six weeks.

#OTD in 2009, the final #Hubble servicing mission launched. SM4 had an ambitious list of tasks designed to bring Hubble to the apex of its scientific capabilities and ensure it would operate for many years to come. (1/3) 🧵

During SM4 astronauts conducted five spacewalks to install two new instruments, repair two other instruments, and replace key components like gyroscopes and batteries. They also prolonged its life by boosting Hubble to a higher orbit. (2/3)

SM4 left Hubble at the peak of its scientific capability, and prepared it for many years of further scientific discovery. Hubble is now expected to continue science operations well into the 2030s. Credit: NASA (3/3)

This pair of galaxies, NGC 2292 and NGC 2293, is beginning to collide, which has started the formation of new stars. These new stars appear like blue pearls in the dusty arm along the bottom.

Still under construction in Chile, Rubin Observatory was designed to understand the nature of dark matter and dark energy, and map the Milky Way. The observatory (first image) will have a fast-moving telescope—mount shown in the second image: https://rubinobservatory.org

In the middle of a large round room that is lined with teal-colored steel is a large round telescope mount. Below the mount, humans are standing, dwarfed by the size of the mount.

NASA's Roman Space Telescope could help researchers detect the universe’s FIRST STARS using the wide field of view and rapid survey speed of the upcoming observatory. (1/6) 🧵

The universe’s earliest stars, known as Population III stars, are notoriously hard to detect with even our most powerful observatories due to their great distance and short lifetime. They were made almost entirely of hydrogen and helium. (2/6)

will not seek intact stars. Instead, astronomers will hunt for signs of Pop III stars that have been shredded by black holes, creating a bright and energetic phenomenon known as a tidal disruption event (TDE). (3/6)

@spacetelescope@astrodon.social avatar

TDEs generate light in many wavelengths. The further we look into the early universe, where these early stars primarily reside, the more the optical and UV light is redshifted, into near-infrared wavelengths visible to Roman. (4/6)

“Roman can go very deep and yet cover a very big area of the sky. That's what's needed to detect a meaningful sample of these TDEs,” said Jane Dai, professor of astrophysics at the University of Hong Kong. (5/6)

With this proposed strategy for identifying Pop III stars, there’s an opportunity to explore more of the universe’s mysteries, opening up numerous opportunities to better understand not only the early universe, but also galaxies closer to home. (6/6)

Researchers using may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system. (1/6) 🧵

The much thinner blankets of gas that almost certainly surround some small, rocky exoplanets have remained elusive. Researchers think they may have finally caught a glimpse of a volatile-rich atmosphere surrounding a rocky planet—55 Cancri e. (2/6)

Light emitted by the hot, highly-irradiated exoplanet 55 Cancri e shows compelling evidence for an atmosphere, probably rich in carbon dioxide or carbon monoxide, which may be bubbling from a vast ocean of lava covering the planet’s surface. (3/6)
