From Madison VanWyngarden: There’s no need to storm Area 51 for evidence of UFOs, in today’s bite we explore the first detection of a UFO (ultra-fast outflow) in a quiescent galaxy! ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/30/ufo-sighting-in-a-dead-galaxy/

UFO Sighting in a Dead Galaxy!

There’s no need to storm Area 51 for evidence of UFOs, in today’s bite we explore the first detection of a UFO (ultra-fast outflow) in a quiescent galaxy!

From Chris Layden: NASA’s SPHEREx mission is collecting an infrared spectrum for every point in the sky. Which could revolutionize our understanding of cosmic inflation, galaxy formation, and how ices drive planet formation and surface chemistry. ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/15/spherex_summary/

SPHEREx: the niftiest space telescope you may not have heard of

NASA’s SPHEREx mission is collecting an infrared spectrum for every point in the sky. That data set could revolutionize our understanding of cosmic inflation, galaxy formation, and how ices drive plan...

From Nicki Bond: What happens when protoplanetary disc systems stop following the rules? Today’s paper looks at how stars with protoplanetary discs in the Upper Scorpius Region experience a mid-life crisis and behave unexpectedly. ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/14/the-protoplanetary-mid-life-crisis/

The Protoplanetary Mid-life Crisis

What happens when protoplanetary disc systems stop following the rules? Today’s paper looks at how some stars with protoplanetary discs in the Upper Scorpius Region experience a mid-life crisis and be...

From Annika Salmi: A spacecraft mission to Saturn’s moon Enceladus found unexpectedly high methane in its ice plumes. A new Nature Astronomy study shows current models can’t reliably distinguish that methane from purely non-biological sources. ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/13/template-post-34/

Telling Aliens from Weird Chemistry on Ocean Planets

A spacecraft mission to Saturn's moon Enceladus found unexpectedly high methane in its ice plumes, fueling speculation about life in its hidden ocean. A new Nature Astronomy sutdy shows current models...

From Flavia Pascal: We’re trying to find life beyond Earth… but we still can’t fully agree on what life actually means. So what happens when you try to solve one of science’s biggest questions in a very multilingual group chat? ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/06/case-for-interdisciplinary-science/

What is life, really? A case for interdisciplinary science

We’re trying to find life beyond Earth... but we still can't fully agree on what life actually means. Astronomers, chemists, and biologists all approach it from different angles and they don't always ...

From Julie Kiel Holm: Seven hot exoplanets were not as windy as they should’ve been. This puzzle led researchers to be the first ones to measure the magnetic field strength on exoplanets. ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/07/07/hot-jupiters-magnetic-fields/

Do Exoplanets Have Auroras?

Seven hot exoplanets were not as windy as they should've been. This puzzle led researchers to be the first ones to measure the magnetic field strength on exoplanets.
