Undersea telescope seeks out dark matter

More than 125 of these curious soccer ball-sized glass spheres hang near the floor of the Mediterranean Sea. Even though they're deep underwater, they're keeping a constant vigil for neutrinos, particles that may be evidence of dark matter, supernovae, and neutron stars far off in intergalactic space. Eventually, the Cubic Kilometer Neutrino Telescope (KM3NeT) will ...

OrbitFab secures National Science Foundation funding to propel its satellite refueling tech to space

On-orbit satellite refueling technology is closer than ever to a practical reality, which could help immensely with the cost and sustainability of orbital businesses. Startup OrbitFab, a 2019 TechCrunch Battlefield finalist, is one of the companies working to make orbital refueling a reality, and it just secured a new contract from the National Science Foundation’s ...

NASA’s Mars helicopter almost ready for take off

The new Mars rover Perseverance, set to launch in July for a February 2021 landing, will be outfitted with its own small helicopter. NASA engineers at Kennedy Space Station recently put the chopper through its paces, marking the last time they'll spin it up before landing on the red planet. From Kennedy Space Center:

The ...

“Old gas blob from Uranus found in vintage Voyager 2 data”

Yes, that is actually Space.com's brilliant headline on this story about a new discovery from data collected in 1986 by NASA's intrepid spacecraft. When the probe neared Uranus (heh heh), it measured the planet's surrounding magnetic field. Recently, NASA scientists Gina DiBraccio and Daniel Gershman analyzing Voyager's old data found a "wobble" in Uranus's magnetosphere ...

NASA’s stunning image of our galactic center

Last July, NASA released this wonderful composite image of the galactic center of the Milky Way.

The central region of our galaxy, the Milky Way, contains an exotic collection of objects, including a supermassive black hole weighing about 4 million times the mass of the Sun (called Sagittarius A*), clouds of gas at temperatures of millions ...

NASA: No, that UFO plainly seen in our space observatory footage isn’t a UFO

NASA's STEREO (Solar TErrestrial RElations Observatory) research platform consists of two orbiting spacecraft that collect stereoscopic data about the sun and the eruptions of magnetized plasma during coronal mass ejections (CMEs). Last month, UFO buffs spotted a strange object in data acquired by STEREO, specifically what appears to be a wheel-shaped UFO. The footage ...

OneWeb confirms layoffs and potential launch schedule delays amid reported bankruptcy considerations

Satellite operator OneWeb has confirmed that its workforce has been reduced via layoffs, after TechCrunch learned that it reduced its workforce by as much as 10 percent this week. The company did not confirm the total size of the layoff, but provided a statement to TechCrunch regarding the current state of its operations, and citing ...

Japanese spacecraft fired cannonball into asteroid

The Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft fired a copper cannonball into Ryugu, an 850 meter-wide near-Earth asteroid. The 2 kilogram "Small Carry-on Impactor," a bit larger than a tennis ball, hit the asteroid at approximately 7,200 kilometers/hour and blew out a 14.5 meter wide crater with a depth of .6 meters. After a ...

NASA and SpaceX targeting mid-to-late May for first astronaut launch, despite coronavirus pandemic

NASA and SpaceX issued a media accreditation invitation on Wednesday for their Demonstration Mission 2 (aka Demo-2) commercial crew launch – the first in the commercial crew program that will carry actual astronauts to space. The invite includes the current proposed timeframe for the mission, listed as no “no earlier than mid-to-late May.” Reports from ...

Physicist Freeman Dyson’s alien megastructure legacy

In 1960 during the early days of the search for extraterrestrial intelligence, theoretical physicist Freeman Dyson, who died last month, wrote an article titled "Search for Artificial Stellar Sources of Infrared Radiation" for the journal Science. He posited that "if extraterrestrial intelligent beings exist and have reached a high level of technical development, one ...
