    "It's the only launch vehicle that can meet the orbit, the schedule and the cost to achieve something unprecedented with emerging technology."A history-making robotic rescue mission scheduled to launch next year will fly on a rocket dropped from a plane.In September, NASA announced that it has chosen Arizona company Katalyst Space Technologies to boost the altitude of its Neil Gehrels Swift Observatory, a space telescope whose orbit has gotten dangerously low since its November 2004 launch...The $500 million Swift observatory was built by Orbital Sciences, a company that in 2014 became Orbital ATK, which was then acquired by Northrop Grumman...
  • Astronomy Picture of the Day - Tails of Comet Wierzchoś

    Explanation: Some comets are regular guests of our solar neighborhood; others come by only once, never to return. We won’t have another chance to see Comet C/2024 E1 (Wierzchoś), which is currently making its way through the inner Solar System. The hyperbolic orbit of this comet indicates that it will likely become an interstellar traveler. Comet Wierzchoś is today near its closest approach to the Earth, passing roughly the same distance from the Earth as is the Sun. The featured 30-minute exposure was taken last week in Chile and shows a 5-degree long ion tail as well as three shorter...
  • When Quantum Physics Hit A Dead End, GPT-5.2 Found a Hidden Door

    NDTV Profit ^ | February 16, 2026 | Yukta Baid
    OpenAI's GPT-5.2 has derived a new formula for gluon interactions, overturning assumptions of zero amplitude and advancing theoretical physics. For a long, long time physicists treated this interaction as a cosmic impossibility — a mathematical dead end so absolute it was taught almost with the certainty of Newton's laws and the elegance of Einstein's equations. Zero, in quantum physics, isn't a shrug; it's a verdict. And this particular verdict had stood unchallenged for decades. But every so often, science gets a jolt — a falling apple, a bending beam of starlight… or, in 2026, an AI model that refuses to...

    Space Daily ^ | Feb 02, 2026 | Robert Sanders for Berkeley News
    Of the more than 4,500 stars known to have planets, one puzzling statistic stands out. Even though nearly all stars are expected to have planets and most stars form in pairs, planets that orbit both stars in a pair are rare. Of the more than 6,000 extrasolar planets, or exoplanets, confirmed to date - most of them found by NASA's Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) - only 14 are observed to orbit binary stars. There should be hundreds. Where are all the planets with two suns, like Tatooine in Star Wars? ... ... Over time,...

    Scientists watching the nearby Fomalhaut star system have directly seen two protoplanets smash together for the first time. Then, they saw it happen again...The Fomalhaut system is no stranger to such crashes. It's famously known as the "Eye of Sauron" due to its resemblance to the fiery, all-seeing eye from J.R.R. Tolkien's Lord of The Rings franchise. The likeness comes from the spectacular dust belt that surrounds Fomalhaut at a distance of 133 astronomical units (AU), with one AU being equal to 93 million miles (150 million km) — the average distance between the sun and Earth.

    Jupiter is slightly smaller and flatter than scientists thought for decades, a new study finds. Researchers used radio data from the Juno spacecraft to refine measurements of the solar system's largest planet. Although the differences between the current and previous measurements are small, they are improving models of Jupiter's interior and of other gas giants like it outside the solar system, the team reported Feb. 2 in the journal Nature Astronomy. "Textbooks will need to be updated," study co-author Yohai Kaspi, a planetary scientist at the Weizmann Institute of Science in Israel, said in a statement. "The size of Jupiter...

    A monster sunspot is taking aim at Earth after firing off dozens of powerful flares Sunday and Monday (Feb. 1-2) — including the most intense solar eruption in years. Elevated geomagnetic activity — possibly resulting in vibrant northern lights at lower latitudes than usual — is possible Thursday (Feb. 5), according to an alert from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC). However, it's still too soon to know for certain. The sunspot, called region 4366, appeared suddenly several days ago and has rapidly grown to roughly half the size of the infamous Carrington Event sunspot,...

    BREAKING: SpaceX wants to turn Space into the World’s Biggest AI Data Center. • SpaceX is seeking approval to launch and operate up to one million satellites designed to function as orbital data centers. • These satellites would provide massive computing power to support advanced artificial intelligence and data processing. • The system would rely on near constant solar energy in space, reducing operating costs and environmental impact compared to Earth based data centers. • Satellites would operate between 500 km and 2,000 km in altitude, across multiple orbital shells, to handle global demand. • High speed laser links would...

  • Yosemite’s Rare “Firefall” Only Happens Once a Year—Here’s What to Know About This Thrilling Phenomenon

    AFAR Magazine ^ | January 21, 2026 | AFAR Magazine Staff
    Every year from mid- to late February, the setting sun hits Yosemite’s Horsetail Fall along the eastern edge of the soaring El Capitan at just the right angle, creating the illusion that the 1,575-foot waterfall is on fire. This Yosemite National Park phenomenon, aka “firefall,” is ultra-popular, and this year is expected to be even more crowded. For the first time since 2021, park reservations are not required to visit Yosemite during firefall. The past 12 months have been tumultuous for the National Park Service, with a 43-day government shutdown, changing free-entry days, and price increases. Now, its rangers will...

    Explanation: A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That's twice the size of our own barred spiral Milky Way. This sharp image from the James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals stunning details of this magnificent spiral in infrared light. Webb's field of view stretches about 60,000 light-years across NGC 1365, exploring the galaxy's core and bright newborn star clusters. The intricate network of dusty filaments and bubbles is created by young stars along spiral arms winding from the galaxy's central bar....

  • Astromony Picture of the Day - NanoSail-D2

    NASA ^ | 2 Jan, 2026 | Image Credit & Copyright: Ralf Vandebergh
    Explanation: In 2011, on January 20, NASA's NanoSail-D2 unfurled a very thin and very reflective 10 square meter sail becoming the first solar sail spacecraft in low Earth orbit. Often considered the stuff of science fiction, sailing through space was suggested 400 years ago by astronomer Johannes Kepler, who had observed comet tails blown by the solar wind. But modern solar sail spacecraft designs, like NanoSail-D2, Japan's interplanetary spacecraft IKAROS, or the Planetary Society's Lightsail A, rely on the small but continuous pressure from sunlight itself for thrust. Glinting in the sunlight as it circled planet Earth, NanoSail-D2's solar sail...
