Ultra-deep imaging from the Isaac Newton Telescope resolves IC 1101's faint outer edge at 520 kiloparsecs across, with 3.4 trillion solar masses in stars.

Webb found Beta Pictoris d by reading its atmosphere's chemical fingerprint, a first for exoplanet discovery, while a separate imaging study independently confirmed it.

ESO's Very Large Telescope captured the clearest-ever image of Betelgeuse B, showing the long-sought companion is 2.6 to 3.1 times the sun's mass.

A dwarf-galaxy transient first spotted in 2019 developed radio emission so bright, years later, that a Chinese-led team says it may define a new class of relativistic explosion.

New 3D simulations matched against 1990s Magellan imagery suggest some Venusian rift valleys are widening 3 to 10 centimeters a year, indicating recent tectonic activity.

Skyroot's Vikram-1 rocket reached a 450 km orbit on its July 18 debut flight, making India the third country with private orbital launch capability.

Ultraviolet spectroscopy from Hubble confirmed four white dwarfs hiding behind red dwarf companions within 65 light-years of Earth, one first suspected 27 years ago.

A low-mass black hole in a spiral galaxy 1.8 billion light-years away has stayed radio-bright for at least eight years, a transition astronomers say has never been observed before.

Washington startup Besxar is flying microwave-oven-sized 'Fabship' pods on Falcon 9 boosters, the first of 12 SpaceX flights testing whether the vacuum of space can produce purer semiconductor substrates.

Rocket Lab agreed to buy satellite operator Iridium for $54 a share, an $8 billion deal that would let it build, launch, and operate its own constellations.

James Webb's NIRSpec spectrograph measured isotopic ratios in interstellar comet 3I/ATLAS as it left the inner solar system, pointing to an origin during the universe's 'cosmic noon.'

Rocket and aircraft integration is complete for the June 27 air-launch of Katalyst's LINK servicer, riding the final flight of Northrop Grumman's Pegasus XL to reboost the sinking Swift Observatory.
