The science behind the sky: black holes, exoplanets, relativity, and how the universe works
Astronomers found two separated, chemically different rings of vaporized rock around white dwarf J1328−1450. Here’s what the spectrum proves—and what remains a proposal.
A new study makes intact, concentrated HCN delivery by comet impact look exceptionally rare. Here is what that narrow result does—and does not—say about life on early Earth.
NASA has confirmed UVEX for its build phase with a $590 million total lifecycle cost and a commitment to launch by January 2031. Here’s what KDP-C actually changes.
Rubin found 2026 ED138 in a crowded Milky Way field. Here’s why it is a dwarf-planet candidate, how precovery reached 2016, and what infrared follow-up must settle.
CTAO-North has completed its four-telescope LST sub-array on La Palma. Here is why synchronized gamma-ray views matter—and why commissioning still comes next.
JWST used transit spectroscopy to map differences around WASP-17 b’s atmospheric limb. Here’s what the “transmission strings” method actually measured.
Francis Halzen’s 2026 Physics Nobel recognizes IceCube, the Antarctic detector that opened a new way to study violent cosmic sources with neutrinos.
NASA selected PRIMA as the first Probe Explorer to enter Phase B. Here’s what that milestone means, what far-infrared astronomy can reveal, and what still must happen before implementation.
IRAS 18293−0941 is the Milky Way’s first convincing microblazar candidate. Here’s what the one-sided jet, 11.38-day orbit, and possible PeV link do—and do not—show.
Hubble and Webb found 27 new trans-Neptunian objects, including one just 5 km wide. Here’s why fewer tiny worlds than expected matters for planet formation.
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.
