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.

in 2009, the final 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)

Dwarf galaxy UGC 5340 shines with thousands of ultraviolet-bright stars (colored blue), making it a perfect target for a Hubble survey of 50 nearby, star-forming galaxies. A particularly active pocket of rapid star birth appears in the lower right corner: https://bit.ly/4aq6HU2

The Kitt Peak National Observatory, a collection of ground-based observatories for nighttime visible and infrared astronomy, left, is in Arizona. It produced the image at right of the Pleiades cluster. More: https://noirlab.edu/science/programs/kpno

Four large blue stars surrounded by interstellar blue clouds sit at top center, bottom center, left center and lower right. Other stars that appear slightly whiter and smaller are near the four, toward the bottom right of the image. Behind these stars is a black background filled with smaller, redder stars.
