Astronomy Jargon 101: Eclipsing Binary
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll be seeing double with today’s topic: eclipsing binaries!
Our galaxy hosts loads of binary stars. So much so that the majority of all stars in the galaxy are members of a binary system. Astronomers can only find most binary systems through intense scrutiny, either by having a telescope big enough to reveal two or more stars where we once thought there was only one, or by using spectroscopy to notice the wiggling motion of one star caused by the orbit of a hidden companion.
Strange twin asteroids, the youngest ever seen, likely broke apart just 300 years ag
Scientists spotted two space rocks that may be Earth's freshest asteroid neighbors, but have to wait until 2033 to see them again.
Greenland lost enough ice in last 2 decades to cover entire US in 1.5 feet of water
Satellite data shows that Greenland’s ice sheet has lost enough water over 20 years to submerge the entire United States.
International Astronomical Union launches new center to fight satellite megaconstellation threat
The International Astronomical Union (IAU) has launched a new center to fight the threat of satellite megaconstellations, which it now describes as worse than urban light pollution.
You can see the SpaceX Falcon 9 booster on a collision course with the moon in a live webcast today
A SpaceX Falcon 9 booster will crash into the moon on March 4, and you can track the rogue rocket during live webcasts on Feb. 7 and Feb.
Rogue black hole spotted on its own for the first time
Astronomers may have for the first time detected and measured the mass of an isolated stellar-mass black hole, a new study finds.
The First Rogue Black Hole has Been Discovered, and it’s Only 5,000 Light-Years Away
Microlensing strikes again. Astronomers have been using the technique to detect everything from rogue planets to the most distant star ever seen. Now, astronomers have officially found another elusive object that has long been theorized and that we first reported on back in 2009 but has never directly detected – a rogue black hole.
Watch SpaceX launch a US spy satellite and land a rocket in this mesmerizing drone video
A stunning new video from SpaceX captures what it's like to watch a rocket launch and then witness the booster return to Earth, all from mid-air.
Ancient evils arise in IDW's new 'Transformers: War's End' comic book miniseries
IDW Publishing rolls out a turbulent new "Transformers: War's End" miniseries in February.
'John Carter of Mars' blasts back to Barsoom in new comic series from Dynamite
Dynamite Entertainment is releasing a new “John Carter of Mars” comic book title in spring 2022.
Titan Books celebrates vintage 'Flash Gordon' comic strips in a deluxe new collection
Titan Books delivers another deluxe volume of classic “Flash Gordon” newspaper strips on February 15
Scientists discover lost range of 'supermountains' three times longer than the Himalayas
Scientists detected two ancient ranges of 'supermountains' that criss-crossed the Earth hundreds of millions of years ago — and may have jump-started animal evolution.
Astronomy Jargon 101: Elliptical Galaxy
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll try to get back in shape with today’s topic: elliptical galaxies!
Elliptical galaxies are the retirement centers of the universe. They are filled with old, red stars and have very little active star formation. Even if they wanted to, they couldn’t make more stars, since they have relatively thin stores of interstellar gas and dust. The stars inside ellipticals are just sitting there, slowly burning through their reserves of hydrogen, dying off one by one.
US Space Force's 'Orbital Prime' project aims to attack space debris by recycling or removing junk
A new U.S. Space Force video "demands action" on space debris and asks the private sector for their help cleaning up the growing space mess.
Lightning bolt breaks record for longest ever recorded
Storms in the U.S. and Uruguay set new records for longest lightning bolt and longest-duration lightning flash.
NASA's James Webb Space Telescope is cooling down for its next trick: Observing the universe
It's been a whirlwind 38 days in space for the James Webb Space Telescope, but its chief scientist says the mission is well on track to uncover the universe soon.
The Space Shuttle was Originally Hoped to be a Fully Reusable two-Stage Rocket
For anyone old enough to remember the 1980s, the Space Shuttle was an iconic symbol of spaceflight. For thirty years (1981-2011), this program flew 135 missions, which consisted of orbital science experiments, deploying satellites, launching interplanetary probes, participating in the Shuttle-Mir program, deploying the Hubble Space Telescope (HST), and constructing the International Space Station (ISS). There were also tragedies along the way, such as the Challenger (1986) and Columbia disasters (2003).
Astra scrubs 1st Florida launch attempt due to faulty 'range asset'
Astra planned to launch the ELaNa 41 mission for NASA today (Feb. 5) from Florida's Cape Canaveral Space Force Station but was thwarted by an issue at the launch range.
A Supercomputer Gives Better Focus to Blurry Radio Images
With better computers comes more battery imagery. Or at least that’s true most of the time. Supercomputers are extraordinarily good at image processing, so it’s normally worth it when a new algorithm comes along that they can turn their attention to. That’s exactly what happened with an algorithm recently developed by Ph.D. student Frits Sweijen and his colleagues at Leiden University. They used several supercomputers’ image processing power to simulate and enhance the resolution of radio images captured by the International LOFAR telescope.
Live coverage: Astra readies for its first launch from Cape Canaveral
