Missions, discoveries, and the science of exploring our solar system and beyond.
A super-Earth just 25 light-years away sits in its star's habitable zone — but teeters on a razor's edge where its atmosphere co…
This June, Venus and Jupiter shine together after sunset, the Moon covers Venus, and the Summer Triangle rises. NASA's complete Ju…
NASA-backed scientists found Earth got phosphorus and nitrogen from nearby space rocks, not distant comets. Jupiter's gravity was …
NASA spotted a glowing X-ray dot 11.8 billion light-years away that could finally explain hundreds of mysterious 'little red dots'…
Hubble caught spiral galaxy M88 mid-journey to the Virgo Cluster's core, where colossal forces will slowly strip away its gas and …
The James Webb telescope stared at a rocky super-Earth 48 light-years away and found total darkness — no air, no crust, just anc…
Earth leaks radio waves into space every day. A top radio astronomer says alien civilisations are doing the same — and we alread…
One gravitational wave out of 28 may carry dark matter's hidden fingerprint. Scientists found a clue inside a black hole crash tha…
A new radio map of the Milky Way magnetic field reveals a giant diagonal twist where the galaxy's invisible field flips the wrong …
Earth's surface is warming, yet the upper atmosphere keeps cooling. Scientists have finally cracked the strange physics behind the…
NASA's MAVEN spotted the Zwan-Wolf effect at Mars, a space squeeze never seen in any planet's air before. It hints at how the Sun …
Hubble caught NGC 1266 stuck between two lives. A black hole inside the galaxy is choking off new stars before they can even be bo…
A 60-year mystery about why space around the Milky Way looks too calm is finally solved. Galaxies near us form a giant flat sheet,…
Scientists finally know why Venus has a giant 6000-km cloud wall. It is the biggest atmospheric shock found anywhere in the solar …
NASA's Roman Space Telescope launches September 2026 to hunt hidden planets near the Milky Way's busy core, and Hubble has now map…
Five years in, NASA's Perseverance rover reached Mars' unexplored western frontier — and turned its camera on itself, revealing …
A massive galaxy spotted by the James Webb Space Telescope shows zero rotation just 2 billion years after the Big Bang — a trait…
A Brown University team shows the cosmological constant may be topologically protected against quantum corrections — just like t…
A deep learning tool just re-measured 28 comets and found long-period comets are far larger than expected — rewriting what we kn…
Earth's orbit wobbles, tilts, and stretches on 100,000-year cycles — triggering every ice age in history. Here's what Milankovit…
Mars tugs Earth closer to the Sun every 2.4 million years, stirring the deep ocean and warming the climate — a cosmic rhythm loc…
After 49 years in space, Voyager 1 just had a key instrument shut off to save power. Here's why NASA made this sacrifice — and w…
NASA's Hubble captured NGC 3137, a spiral galaxy 53 million light-years away that lives in a group strikingly similar to our own M…
A new study says the Large Magellanic Cloud has never visited the Milky Way before — but a rival team disagrees. Here's what the…
Astronomers found a galaxy with two generations of energy beams: one ancient and cold, the other just waking up. And a strange tai…
Fred Hoyle coined 'Big Bang' in 1949 to mock a rival theory. The universe didn't explode — space expanded. And the theory lacked…
A new Nature Astronomy study used 10 isotope systems simultaneously to show Earth built itself entirely from inner Solar System ma…
French physicist Jean-François Geneste proposes dropping a foundational axiom of geometry to build a universe model that unifies …
NewCluster tracks 10 chemical elements, cosmic dust, and galaxy motion inside a Virgo-sized cluster at 68-parsec resolution — fi…
For the first time ever, astronomers caught a comet reversing its own spin — driven by gas jets on its surface. Here's what come…
