    Explanation: How is RXJ0528+2838 creating such shock waves? A recently discovered white dwarf star, the farther left of the two largest white spots, RXJ0528+2838, was found 730 light-years away from Earth. Most stars, when done fusing nuclei in their cores for energy, become red giant stars, the cores of which live on as faint dense white dwarfs that slowly cool down for the rest of time. White dwarfs are so dense that the only thing that stops them from collapsing further is quantum mechanics. In about 5 billion years, our Sun will become a white dwarf, too. The featured image,...

    Explanation: What would it be like to fly free in space? About 100 meters from the cargo bay of a space shuttle, Bruce McCandless II was living the dream -- floating farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured, was floating free in space. During Space Shuttle mission 41-B in 1984, McCandless and fellow NASA astronaut Robert Stewart were the first to experience such an "untethered space walk". The MMU worked by shooting jets of nitrogen and was used to help deploy and retrieve satellites. With a mass over 140...

    Explanation: Roses are red, nebulas are too, and this Valentine's gift is a stunning view! Pictured is a loving look at the Rosette Nebula (NGC 2237): a cosmic bloom of bright young stars sitting atop a stem of glowing hot gas. The rose’s blue-white speckles are among the most luminous stars in the galaxy, with some burning millions of times brighter than the Sun. Their stellar winds sculpt the famed rose shape by pushing gas and dust away from the center. Though only a few million years old, these massive stars are already nearing the end of their lives, while...

    Explanation: Dwarf galaxies NGC 147 (left) and NGC 185 stand side by side in this deep telescopic portrait. The two are not-often-imaged satellite galaxies of M31, the great spiral Andromeda Galaxy, some 2.5 million light-years away. Their separation on the sky, less than one degree across a pretty field of view toward the constellation Cassiopeia, translates to only about 35 thousand light-years at Andromeda's distance, but Andromeda itself is found well outside this frame. Brighter and more famous satellite galaxies of Andromeda, M32 and M110, are seen much closer to the great spiral. NGC 147 and NGC 185 have been...

    Starlab — being built by Voyager Space and Airbus through a joint venture, alongside partners including Northrop Grumman and Hilton — is planned to launch on a single mission of SpaceX’s mammoth rocket. Starlab represents one of the earliest commercial customers to order a Starship launch from SpaceX. The companies did not disclose the launch contract’s value. The station is one of several currently in development by U.S. companies, as NASA prepares to retire the International Space Station in 2030. Voyager and Airbus are targeting as early as 2028 for Starlab’s launch. The space station’s four-year development and construction timeline...

    James Cobban Space Nerd since 19569h Why is liquid hydrogen so challenging to handle when fueling rockets, and what special techniques are used to prevent leaks? The most effective way to avoid the challenges of using liquid hydrogen is to not use liquid hydrogen. There is no galactic police officer holding a phaser forcing NASA to use liquid hydrogen. There is no law of physics which says rockets must use liquid hydrogen. What.there are is a bunch of collosally ignorant politicians being bribed to insist that NASA piss away billions of tax dollars on technology which killed fourteen American heroes....

    The Daily Mail UK ^ | February 10, 2026 | Chris Melore
    Tapes containing the original, high-quality transmission of the Apollo 11 moon landing were wiped after being quietly shelved in an unmarked storage area by NASA. While other recordings of the historic 1969 mission survived, the revelation that at least some moon landing video disappeared has fueled wild conspiracies that NASA has been covering up what astronauts saw or even that the whole mission was faked. Now, the truth about these 'erased' tapes has been revealed by Tim Dodd, better known as the 'Everyday Astronaut' on YouTube, who said the lost footage was only a set of backup magnetic tapes containing...

    Explanation: Dark, smooth regions that cover the Moon's familiar face are called by Latin names for oceans and seas. That naming convention is historical, though it may seem a little ironic to denizens of the space age who recognize the Moon as a mostly dry and airless world, and the smooth, dark areas as lava-flooded impact basins. For example, this telescopic lunar vista, looks over the expanse of the northwestern Mare Imbrium, or Sea of Rains and into the Sinus Iridum, the Bay of Rainbows. Ringed by the Jura Mountains (montes), the bay is about 250 kilometers across. Seen after...

    Explanation: How many sunspots can you see? The central image shows the many sunspots that occurred in 2025, month by month around the circle, and all together in the grand central image. Each sunspot is magnetically cooled and so appears dark -- and can last from days to months. Although the featured images originated from NASA's Solar Dynamics Observatory, sunspots can be easily seen with a small telescope or binoculars equipped with a solar filter. Very large sunspot groups like recent AR 4366 can even be seen with eclipse glasses. Sunspots are still counted by eye, but the total number...

    Explanation: Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the creative featured image was captured as a composite from three separate exposures. The setting is a summit of the Austnesfjorden (a fjord) close to the town of Svolvear on the Lofoten islands in northern Norway. The year was 2014. This year, our...

    Astronauts headed into orbit — and toward the moon — will soon be able to bring their personal smartphones along for the ride. NASA announced this week that crews assigned to upcoming missions, including Crew-12 and Artemis II, will be allowed to fly with modern smartphones, marking a shift from longtime rules that required astronauts to leave personal devices behind while living aboard the International Space Station. In a post on X, NASA Administrator Jared Isaacman said the change is meant to help crews document historic moments and stay connected with loved ones back on Earth. ... Until now, astronauts...
  • Astronomy Picture of the Day - Miranda Revisited

    Explanation: What is Miranda really like? Visually, old images from NASA's Voyager 2 have been recently combined and remastered to result in the featured image of Uranus's 500-kilometer-wide moon. In the late 1980s, Voyager 2 flew by Uranus, coming close to the cratered, fractured, and unusually grooved moon -- named after a character from Shakespeare’s The Tempest. Scientifically, planetary scientists are using old data and clear images to theorize anew about what shaped Miranda's severe surface features. A leading hypothesis is that Miranda, beneath its icy surface, may have once hosted an expansive liquid water ocean which may be slowly...

    Explanation: An unusually active sunspot region is now crossing the Sun. The region, labelled AR 4366, is much larger than the Earth and has produced several powerful solar flares over the past ten days. In the featured image, the region is marked by large and dark sunspots toward the upper right of the Sun's disk. The image captured the Sun over a hill in Zacatecas, Mexico, 5 days ago. AR 4366 has become a candidate for the most active solar region in this entire 11-year solar cycle. Active solar regions are frequently associated with increased auroral activity on the Earth....

    Explanation: Peering from the shadows, the Saturn-facing hemisphere of tantalizing inner moon Enceladus poses in this Cassini spacecraft image. North is up in the dramatic scene captured during November 2016 as Cassini's camera was pointed in a nearly sunward direction about 130,000 kilometers from the moon's bright crescent. In fact, the distant world reflects over 90 percent of the sunlight it receives, giving its surface about the same reflectivity as fresh snow. A mere 500 kilometers in diameter, Enceladus is a surprisingly active moon. Data and images collected during Cassini's flybys have revealed water vapor and ice grains spewing from...

    Explanation: Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light...
  • Astronomy Picture of the Day - NGC 1275 in the Perseus Cluster

    NASA ^ | 5 Feb, 2026 | Image Credit & Copyright: Michal Wierzbinski, Hellas-Sky
    Explanation: Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. Narrowband image data used in this sharp telescopic image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. The filaments persist in NGC 1275, even though the turmoil of galactic collisions should destroy them. What keeps...
