Feb 23rd, 2026 - By A galaxy so faint it escaped detection for as long as anyone has been scanning the sky has finally been found. Called CDG-2, this newly identified "ghostly" galaxy may be one of the most dark matter-dominated galaxies ever discovered, with a staggering 99% of its total mass made up of dark matter — a mysterious substance that cannot be seen, touched, or felt. The Hubble Space Telescope, now more than three decades into its mission, played a key role in revealing this cosmic phantom. ... [Read More]

Feb 23rd, 2026 - Arrokoth hangs out around a billion miles out from Pluto. Deep within the Kuiper belt , some small worlds look like they were assembled from two mismatched snowballs pressed together. The poster child is Arrokoth , the "contact binary" visited in 2019 by NASA's New Horizons spacecraft . Its twin lobes share similar colors and volatile ices, and its surface shows relatively modest cratering. What still needed tightening was the how. Did Arrokoth start as two separate bodies that spent eons ... [Read More]

Feb 23rd, 2026 - Time is a crucial concept driving the plot. The lead character, Matthew McConaughey's Cooper, embarks on the space mission to save Earth fully knowing that he'll miss years with his kids — and possibly never return. The events occurring near the black hole, where time passes a lot more slowly than on Earth, end up breaking Cooper's heart. Gargantua's massiveness seems inescapable. How did scientists photograph a black hole? looked like the Gargantua design, we had no way of knowing how ... [Read More]

Feb 22nd, 2026 - On Feb. 22, 1906, German astronomer Max Wolf made a discovery that adjusted astronomers' view of the cosmos and provided proof for the century-old predictions of Joseph-Louis Lagrange. A pioneer in the use of a comparator to examine astrophotographs side-by-side, Wolf had discovered 18 new asteroids within his first two years of searching. Wolf's 1906 discovery was an asteroid that appeared to be linked to Jupiter's orbit, remaining about 60 degrees ahead of it. The first Trojan asteroid to be ... [Read More]

Feb 22nd, 2026 - Follow Earth on Google New observations show a small Saturn moon has generated electromagnetic waves that extend more than 313,000 miles behind it inside Saturn's magnetic field. That newly measured reach reveals a tiny icy world acting as a planetary-scale engine, reshaping how scientists understand the power of small moons. Cassini mapped the wake Cassini's instruments repeatedly encountered the same magnetic disturbance far downstream from Enceladus, tracing a vast electrical wake through ... [Read More]

Feb 22nd, 2026 - Follow Earth on Google Physicists think they may have figured out where an extremely powerful, nearly undetectable particle that hit Earth came from, linking it to the final explosion of a very small black hole. If they are right, that single event could offer new insight into what the universe created in its earliest moments after the Big Bang. The signal itself In 2023, the KM3NeT observatory logged a particle near 220 PeV, a unit equal to a quadrillion electron volts, beneath the ... [Read More]

Feb 22nd, 2026 - The telescope observed the ice giant for a full rotation, revealing how temperature and charged particles vary with altitude. Reading time 2 minutes On January 19, the Webb space telescope stared deep into the chaotic world of Uranus for 17 hours, observing as the faint glow from molecules above the planet's clouds meets its unusual magnetic field. The resulting data helped scientists map Uranus's upper atmosphere in unprecedented detail, revealing new insight into how its tantalizing auroras ... [Read More]

Feb 21st, 2026 - In December 2018, a trio of astronomers –  Scott Sheppard of the Carnegie Institution for Science, David Tholen of the University of Hawaii, and Chad Trujillo of Northern Arizona University – set the record for the most distant object ever discovered in the solar system. Because the small world is located about three times farther from the Sun than Pluto, the researchers dubbed it Farout. Not to be outdone (even by themselves), the same group of boundary pushers announced the ... [Read More]

Feb 20th, 2026 - Sky This Week is brought to you in part by Celestron. Friday, February 20 Once the waxing Moon sets this evening, its disappearance opens up a nice dark window for deep-sky viewing. Lying in far southeastern Lynx, NGC 2683 is 80° high in the southeast at 10 P.M. local time. Also called the UFO Galaxy, NGC 2683 is a nearly edge-on spiral that sits some 16 million light-years away.  The brightest nearby star is actually in the neighboring constellation of Cancer: Simply find magnitude ...

Feb 20th, 2026 - Follow Earth on Google It started as another exoplanet in a group labeled "ordinary." No one expected that a world, once thought to be a mini-Neptune, would reveal traits of a super-Venus and change how we see certain planetary types. Astronomers used JWST data to learn more about an unusual place called Enaiposha, that orbits a red dwarf star about 47 light-years away from the Sun. A surprising "super-Venus" Enaiposha, that also goes by the identifier GJ 1214 b , was first placed in a category ... [Read More]

Feb 19th, 2026 - Built, integrated, tested, and launched in 22 months at under $80 million, the Clementine probe was devised jointly by NASA and the Ballistic Missile Defense Organization, and epitomised the "faster, better, cheaper" management ethos, testing miniaturized sensors, multimode propulsion and attitude-control systems, and gallium arsenide solar cells in deep space. When the spacecraft rose from Space Launch Complex 4 West at California's Vandenberg Air Force Base atop a Titan IIG rocket at 8:34 ... [Read More]

Feb 19th, 2026 - An exotic type of dark matter could explain some of the characteristics of our galaxy's central supermassive black hole, but many cosmologists are leery of the idea At the centre of our galaxy lies a supermassive black hole called Sagittarius A* – but one group of researchers is suggesting it may not be a black hole at all. The team says that it, and other black holes around its size, may actually be clumps of dark matter. Dark matter , so named because it doesn't seem to interact with ... [Read More]
