If Life Exists in Venus' Atmosphere, It Could Have Come From Space

A new study presented at the 2026 LPSC suggests that if life does exist in Venus' clouds, there's a chance it came from Earth.

An Aerobot With ISRU Capabilities Could Explore Venus' Atmosphere for Years

In a new proposal, a team of scientists explores how aerial robotic platforms (areobots) with in-situ resource utilization (ISRU) capability could operate for years in Venus' atmosphere.

The Habitable Worlds Observatory Will Need Astrometry To Find Life

We’re getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we’re looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That’s a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose primary job is to do precisely that. But even capturing a picture and a planet and getting spectral readings of its atmospheric chemistry still isn’t enough, according to a new paper available in pre-print on arXiv by Kaz Gary of Ohio State and their co-authors. HWO will need to figure out how much a planet weighs first.

The Artemis Generation Begins! Artemis II Launches for the Moon

At 06:25 p.m. EDT (03:25 p.m. PDT) on April 1st, the Artemis II mission lifted off from the historic Launch Pad-39B at NASA's Kennedy Space Center in Florida. This mission will send astronauts on a ten-day journey around the Moon and will be the first crewed mission to venture beyond Low Earth Orbit (LEO) since the Apollo Era.

Why Are Supermassive Black Holes Growing So Slowly?

About 10 billion years ago, the growth rate of supermassive black holes began to slow dramatically. To this day, the SMBH growth rate still appears to be low. There are three potential explanations for this, and researchers think they've figured out which explanation fits best.

Astronomers Find a Third Galaxy Missing Its Dark Matter, Validating a Violent Cosmic Collision Theory

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, scientists have found a string of galaxies that seem to be missing their dark matter entirely. The latest in this string, known as NGC 1052-DF9, is described in a new paper, available in pre-print on arXiv, by Michael Keim, Pieter van Dokkum and their team from Yale. It lends credence to a radical theory of galaxy formation known as the “Bullet Dwarf” collision scenario, which has been a controversial idea for the last decade.

The Largest Survey of Exoplanet Spins Confirms a Long-held Theory

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. Using the W.M. Keck Observatory on Maunakea, Hawai'i, a team of astronomers confirmed this relationship by studying dozens of gas giants and brown dwarfs in distant star systems.
