The science behind the sky: black holes, exoplanets, relativity, and how the universe works
FAST and DESI find cosmic star formation fell much faster than neutral atomic hydrogen. Here’s why that mismatch matters for galaxy evolution.
Hubble has found a developing 10-sided wave around Saturn’s south pole. Here’s how it differs from the planet’s long-lived northern hexagon.
LZ has reported one unexplained high-energy interaction at 2.6 sigma—not a dark-matter detection. Here’s what that number means, and what comes next.
Cloud-9’s newest ultra-deep images found no starlight — a stronger limit, not a final proof. Here’s what optical and radio observations each reveal.
Watch NASA’s Roman launch weekend from Austin, Houston, or LA: target time, official updates, no-gear plans, and what happens after liftoff.
NASA’s LRO measured the Falcon 9 impact crater at about 60 feet wide. Repeat views under changing light revealed fresh ejecta and lunar layers.
See a scale model of the Hobby-Eberly Telescope in Austin, understand spectroscopy, and plan the real McDonald Observatory visit near Fort Davis.
DESI Legacy Surveys’ 5.6-trillion-pixel release puts nearly four billion objects in a public viewer. Explore it—and understand why it is a 2D map, not DESI’s 3D survey.
Webb found clay-mineral signatures on Larissa, Galatea, and Neptune’s rings. Here is what that says about ancient icy worlds—not water today.
44 Nysa may be a rare three-lobed contact world with a tiny moon. Here is what the evidence supports, what remains uncertain, and why that matters.
Austin, Houston, and Los Angeles are outside the August 12 eclipse viewing zone. Here’s the accurate North Atlantic experience plan—and the local Perseid alternative.
Host an August 12, 2026 eclipse livestream watch party in Austin, Houston, or Los Angeles with ESA’s Javalambre broadcast and NASA Live timing.
Fermi data reveal a candidate sibling-supernova pair behind the Jellyfish Nebula. Here’s the evidence, the timeline, and what remains unproven.
A 2024 helium signal offers evidence consistent with an atmosphere on LHS 1140 b. Here is what the transit observation shows, why 2025 matters, and what remains unknown.
Saturn will sit near the Last Quarter Moon before dawn on July 7, 2026. Here is why it looks like a star at first glance and what changes with optics.
NOAA now puts the strongest July 4 weekend aurora block on Friday evening locally, but Austin, Houston, and Los Angeles still do not get a clean dark-sky window.
Mercury reaches aphelion on July 1, 2026. Here's what that actually means, why Mercury's orbit is unusually stretched, and why the date matters for beginners.
