Two Planets We've Been Calling Ice Giants May Be Full of Magma
The two planets have been called ice giants for decades. Modeling suggests their interiors may be roiling oceans of magma instead.

Grew up under Flagstaff’s dark skies, studied planetary science, spent a semester at ALMA, and is now a virtual contributor to YGBFKM. Convinced the universe is stranger than we’re told and plans to prove it. Has two cats: Sagan and Fermi.
A Dying Star May Spark an Entire Baby Universe Inside Itself
What if a dying star doesn't collapse into a black hole, but births an entirely new universe instead? The math behind gravastars just got a lot harder to ignore.
A Galaxy Did a Supersonic Cannonball. A Student in the Himalayas Caught the Glow.
A galaxy plowing through near-empty space fast enough to leave a glowing 1.8-million-light-year scar and a student in the Himalayas found it first.
The Pentagon Dropped Its Fourth UAP File Batch, and the Internet Did What the Internet Does
Four agencies. 40 files. One object that might scramble military sensors. The floating brain went viral, but is it really the weirdest thing in this batch?
1952 'Invasion of Washington' Tape May Finally See Daylight
An Air Force briefing about the 1952 UFO invasion of Washington has been sitting in an MIT archive for 74 years. A congressman just found it. What was worth recording?
A House Amendment Would Subpoena Every Federal UAP Record and Put Them Online in 30 Days
A new defense bill amendment would force every federal agency to surrender its UAP records to the National Archives, give a review board subpoena power over the CIA, and set a hard 300-day deadline. It also defines "non-human intelligence" as an operative legal term.
AARO Tracks Genuine UAP by Radar Signature and Infrared. The Pentagon Released Eyewitness Sketches.
A flying potato. Glowing orbs. A 1949 letter to J. Edgar Hoover. The Pentagon's third UAP release spans 77 years of unexplained sightings and zero resolved cases.
The Bar at the Beginning of the Universe
Stellar bars don't survive in gas-rich environments. GN20 is 75 percent gas. It has one anyway.
The Pentagon Dropped 50 More UAP Videos. The Lake Huron File Was Worth the Wait.
The NSA released hundreds of UAP pages days before the Pentagon drop. Many are still heavily redacted and some are decades old.
Rocky, Gaseous, Gaseous, Rocky. The Universe Skipped Astronomy 101.
A star 116 light-years away built its planets in an order that shouldn't exist. What happened out there at the edge?
The End of the Universe
Astronomers say we've been misreading dark energy; the cosmological constant is negative. Not good news for the universe.
Fight Clubs of the Cosmos
Too massive to originate from a single collapsing star, the biggest black holes form from a series of clashes of smaller black holes.
Pond Creature With No Brain and a Better Memory Than Your Neuroscience Textbook
Blocking protein synthesis, which is supposed to erase memory, made a single cell learn faster and remember longer.
The Big Bang Made Two Universes. We Got the One Going Forward.
A math-supported theory proposes that matter exists because the Big Bang created a mirror twin running in reverse. That twin may also explain dark energy.
Hellish Sulfur World Is Off the Charts
A planet 35 light-years away has a sulfur atmosphere that should have burned off billions of years ago. Astronomers had to create a new category to describe it.
No Spin, No Explanation: A Massive Ancient Galaxy Sits Still
A rare non-rotating galaxy spotted by the James Webb telescope. One dramatic collision might explain it.
A World Beyond Pluto Burped Up an Atmosphere
An icy rock out past Neptune is holding onto gas it has no right to hold.
The Pentagon Just Put Its UAP Files Online. Start Watching.
The Pentagon released its first UAP files Friday. The images are murky. The transparency claim is not.
