It’s the question of the hour. On the first day of the month July 1st, the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile spotted an interstellar interloper, which would receive the official designation C/2025 N1 ATLAS or 3I/ATLAS. The ‘I’ is a rare ‘interstellar’ designation, only the third such object known of after 1I/ʻOumuamua and 2/I Borisov. But can we see it? Such a spectacle as actually seeing an interstellar comet would be a true rarity to cross off your skywatching life list.

Stars don’t form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the galaxy at almost absolute zero, emitting essentially no light, and generally making life difficult for astronomers. But, part of how they make life difficult is actually the key to studying them - they have “absorption lines” that detail what kind of material the light is passing through on its way to Earth. A new paper from Harvey Liszt of America’s National Radio Astronomy Observatory and Maryvonne Gerin of the Sorbonne details how tracking those absorption lines via radio astronomy can trace the “dark neutral medium” of interstellar gas throughout the galaxy.

A 2.35 billion year old rock that fell from the sky in Africa is rewriting our understanding of the Moon's past. This ancient meteorite, blasted off the lunar surface has revealed that our closest neighbor remained volcanically active for nearly a billion years longer than scientists previously knew. With its unique chemical fingerprint pointing to deep lunar origins, this rare space rock proves that sometimes the most extraordinary discoveries don't require billion dollar missions, they literally drop into our laps, carrying secrets from space.

Why wait for rare solar eclipses? ESA's Proba mission can now create an artificial solar eclipse once a day. Now, a UK-led mission could do the same trick, but using the Moon's shadow to provide a 48-minute total eclipse once every lunar orbit (29.6 days). Named the Moon-Enabled Sun Occultation Mission (MESOM), the small spacecraft would align its orbit with the Moon, blocking the Sun perfectly, allowing observations of the solar atmosphere.
