OSIRIS-REx weighs 4,650 pounds (or 2,110 kg). On September 8th of 2016, NASA first launched the spacecraft on its 3.8-billion mile mission to land on an asteroid and retrieve a sample. That sample has just returned. Throughout Sunday morning, NASA tweeted historic updates from the sample’s landing site in Utah. “We’ve spotted the #OSIRISREx capsule Read more about After Seven Years, Sample Collected From Asteroid Finally Returns to Earth[…]

[…] Using Solar Orbiter’s Extreme Ultraviolet Imager (EUI), the team of scientists behind the mission was able to record part of the Sun’s atmosphere at extreme ultraviolet wavelengths. The last-minute modification to the instrument involved adding a small, protruding “thumb” to block the bright light coming from the Sun such that the fainter light of Read more about Clever Camera Trick Allows view of Sun’s Corona[…]

Blazars occupy an intriguing spot in the cosmic zoo. They’re bright active galactic nuclei (AGN) that blast out cosmic rays, are bright in radio emission, and sport huge jets of material traveling in our direction at nearly the speed of light. For some blazars, their jets look curvy and snaky and astronomers have questions. […] Read more about Some Galaxies Contain Double Supermassive Black Holes[…]

A pair of astrophysicists at the Rochester Institute of Technology has found via simulations that some black holes might be traveling through space at nearly one-tenth the speed of light. In their study, reported in Physical Review Letters, James Healy and Carlos Lousto used supercomputer simulations to determine how fast black holes might be moving Read more about Simulations suggest some black holes could be moving at nearly one-tenth the speed of light[…]

Virgin Galactic’s VSS Unity, the reusable rocket-powered space plane carrying the company’s first crew of tourists to space, successfully launched and landed on Thursday. The mission, known as Galactic 02, took off shortly after 11am ET from Spaceport America in New Mexico. Aboard the spacecraft were six individuals total – the space plane’s commander and Read more about Virgin Galactic successfully flies tourists to space for first time[…]

Scientists have observed a white dwarf star – a hot stellar remnant that is among the densest objects in the cosmos – that they have nicknamed Janus owing to the fact it has the peculiar distinction of being composed of hydrogen on one side and helium on the other. […] The star is located in Read more about Janus, ‘two-faced’ hydrogen / helium white dwarf star[…]

At 0915 Mountain Time (1515 UTC), the VMS Eve mothership took off from New Mexico’s Spaceport America, carrying its spacecraft to an altitude of 44,500 feet (over 13.5km). Pilots on VSS Unity, which rides along with VMS Eve, then fired its rockets to take its six passengers even higher – to 54.2 miles (over 87.2km) Read more about Virgin Galactic flies final test before opening for business[…]

Commercial Earth-observation companies collect an unprecedented volume of images and data every single day, but purchasing even a single satellite image can be cumbersome and time-intensive. SkyFi, a two-year-old startup, is looking to change that with an app and API that makes ordering a satellite image as easy as a click of a few buttons Read more about SkyFi lets you order up fresh satellite imagery in real time with a click[…]

On March 23, sky observers marveled at a gorgeous display of northern and southern lights. It was a reminder that when our Sun gets active, it can spark a phenomenon called “space weather.” Aurorae are among the most benign effects of this phenomenon. At the other end of the space weather spectrum are solar storms Read more about NASA Reveals What Made an Entire Starlink Satellite Fleet Go Down – movie included[…]

There’s an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long “contrail” of newborn stars, twice the Read more about Blach hole streaking through galaxy leaves wake of new stars[…]

The Bruce Murray Laboratory for Planetary Visualization has completed a 5.7 terapixel mosaic of the surface of Mars rendered at 5.0 m/px. Each pixel in the mosaic is about the size of a typical parking space, providing unprecedented resolution of the martian surface at the global scale. The mosaic covers 99.5% of Mars from 88°S Read more about A super high resolution, Global CTX Mosaic map of Mars[…]

[…] Some of the data was mistaken as noise when first collected up to 40 years ago, and researchers failed to recognize its significance until now. “When everything was calibrated, we saw clearly that the spectra are consistent across all the missions,” announced Lotfi Ben-Jaffel, lead author of the new research published in Planetary Science Journal Read more about Astronomers discover Saturns rings raining down, causing heat in atmosphere.

Virgin Orbit’s days of slinging satellites into space aboard aircraft-launched rockets have come to an end Thursday. After six years in business, Virgin’s satellite launch subsidiary has announced via SEC filing that it does not have the funding to continue operations and will be shuttering for “the foreseeable future,” per CNBC. Nearly 90 percent of Read more about Virgin Orbit officially shutters its space launch operations[…]

Dawn Aerospace CEO Stefan Powell announced today that the company’s Mk-II Aurora spaceplane has received approval from the Civil Aviation Authority of New Zealand for rocket-powered flight. The company is now ready to test the vehicle’s rocket engines with flights beginning next month.

Hundreds of millions of light-years away in a distant galaxy, a star orbiting a supermassive black hole is being violently ripped apart under the black hole’s immense gravitational pull. As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very Read more about A team of physicists devise a model that maps a star’s surprising orbit about a supermassive black hole[…]

You may not realize it in your day-to-day life, but we are all enveloped by a giant “superbubble” that was blown into space by the explosive deaths of a dozen-odd stars. Known as the Local Bubble, this structure extends for about 1,000 light years around the solar system, and is one of countless similar bubbles Read more about We Exist Inside a Giant Space Bubble, And Scientists Have Finally Mapped the magnetic field around it[…]

(Andromeda Galaxy) In the quest to find the outer limits of our galaxy, astronomers have discovered over 200 stars that form the Milky Way’s edge, the most distant of which is over one million light-years away—nearly halfway to the Andromeda galaxy. The 208 stars the researchers identified are known as RR Lyrae stars, which are Read more about Astronomers Find the Edge of Our Galaxy, 1.04m light years away[…]

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star’s gas disk at impossibly high speeds. What’s more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could Read more about Hydrogen masers (jets at 500 km/s) reveal new secrets of a massive star[…]
