Who Needs Jupiter?

The original plan for an upcoming flagship mission to Uranus called for a slingshot around Jupiter. Now that the planet won’t be in the right position at launch time, the spacecraft will need to follow a different path.

Protoplanetary Disk

How early did planets form in the universe? A recent study used simulations to find that planetesimals could have formed significantly earlier than previously thought.

IC 5332

Astrobites reports on JWST observations of dust that has survived being expelled from a galaxy into the circumgalactic medium.

Researchers have discovered a comet-shaped nebula surrounding a pulsar speeding through the remains of its progenitor star.

JWST observations of the most recent interstellar visitor reveal a coma dominated not by water, as expected for solar system comets, but instead carbon monoxide.

ALMA observations of PDS 70

PDS 70c is the first exoplanet known to host a circumplanetary disk, where moons are potentially forming.

Galaxies of Many Colors

Astrobites reports on whether our methods for weighing galaxies can help save cosmology from JWST’s universe-breaking galaxies.

An accreting stellar-mass black hole embedded in a supernova remnant is potentially a powerful cosmic particle accelerator.

Epoch of Reionization

When two galaxies collide, they spark new star formation that can emit tons of powerful radiation. A recent study observes such a system and connects this process to the reionization of the universe.
