Galaxy mergers are not particularly rare, but they are important events. Not only for the galaxies involved, but for scientists trying to piece together how galaxies evolve. Now, astronomers using ALMA have found the earliest example yet of merging galaxies. The pair of merging galaxies in question is called B14-65666, an unwieldy name, but scientifically

When it comes to supersonic aircraft, engineers aren’t afraid to go with a weird design if it will get them a faster plane. In the latest instalment of such feats, NASA’s X-59 QueSST has taken the shape of a pencil with wings. The aircraft’s shape brings with it some interesting questions. For example, if the cockpit
WASHINGTON — Companies involved in NASA’s exploration program agree with a recent estimate by the head of NASA that landing humans on the moon by 2024 will require an additional $20 billion to $30 billion for the agency. NASA Administrator Jim Bridenstine gave that cost estimate in a June 13 interview with CNN, saying that

Scientists have discovered an unexpectedly simple formula that governs one of the most seemingly unknowable limits in physics: determining how much of an electric field a water droplet can withstand before it will burst. This infinitesimal phenomenon has been studied by physicists for decades, but while the overall concept may be easy to imagine, discerning
MUMBAI (Reuters) – From companies building palm-sized satellites to those aiming to propel satellites into space using cleaner fuels, a new wave of space technology startups are mushrooming in India, catching the attention of investors keen to join the space race. Bellatrix Aerospace CEO Rohan Ganapathy stands next to a vacuum chamber at their laboratory
SANTA BARBARA, California — A European Ariane 5 rocket successfully launched two communications satellites June 20. The heavy lift launcher took off from Europe’s spaceport in Kourou, French Guiana, at 5:43 p.m. Eastern, carrying the T-16 satellite for AT&T’s DirecTV business, and the Eutelsat-7C satellite for French operator Eutelsat Communications. The 6,330-kilogram T-16 satellite, built

The observatory now under construction on
There’s something about a bubble of soapy water that causes it to freeze in a peculiar yet beautiful way. The magical-looking reaction has been an internet sensation for years now, and physicists at Virginia Tech think they finally have an explanation. When a normal drop of water ices over, it starts at the coldest point and
When stars are young, they’re often surrounded by a ring of dust and gas known as a protoplanetary disk. Eventually, the material in this disk can clump together, forming everything from planets to asteroids. Now, an international team of researchers has found a young star with thin rings and gaps in the outer part of
WASHINGTON — A new Government Accountability Office report called on NASA to develop a contingency plan to maintain access to the station after next September should commercial crew vehicles suffer additional delays. The June 20 report by the GAO noted that both Boeing and SpaceX are making progress on the development of their commercial crew
Machine Learning For Mental Health Depositphotos Introduction Any disturbance in human behavior has immediate and future consequences and costs. So, when a growing number of humans from across nations suffer from some form of mental illness, the cost and consequences to countries’ economic and societal security understandably skyrocket. This is a crisis that is becoming increasingly
When people come to visit the Nordic island of Sommarøy, they must leave their sense of time at the door. Some choose to do this quite literally, and so, the bridge that connects this small fishing village to the mainland is sprinkled not with lover’s padlocks as you would expect in any other location, but rather,
Just under half a century ago a system of satellites codenamed Hexagon was circling the globe and snapping high-resolution shots of the changing landscape… not to mention a Russian airfield or two. With the Cold War long melted, those images were declassified back in 2002, providing rich pickings for all kinds of research. Now scientists have
SANTA BARBARA, California — An Indian satellite propulsion startup with eventual plans to also build a small launch vehicle has raised $3 million from a group of venture capital investors. Bangalore, India-based Bellatrix Aerospace intends to use the funds to demonstrate its thruster technology in space. IDFC-Parampara, StartupXseed, Karsemven Fund and Survam Partners led the
With a large amount of atmosphere to pass through, light from the Sun (or Moon) reddens tremendously when it’s close to the horizon. Neither the latest sunset of the year nor the earliest sunrise of the year corresponds to the summer solstice. Max Pixel / FreeGreatPicture.com The length of a day on planet Earth might
If you’ve ever felt your eyelids droop for just a fraction of a second during some mundane task — like staring at a computer screen or driving down the highway — you’ve experienced a phenomenon known as “microsleep.” Discover Magazine‘s blog The Crux recently spotlighted the experience, which happens when key parts of the brain
Our search for extraterrestrial intelligence requires spanning distances so vast, sometimes it may feel even worse than finding a needle in a haystack. Since the 1960s, astronomers have combed through billions of radio channels looking for anything out of the ordinary, as this could suggest not only some other form of life, but perhaps also
Great news! Humankind’s greatest-ever engineering project is nearing completion. Soon we will have warmed the Earth enough to get rid of all those pesky ice sheets and other frozen areas. The finish line is in sight. If we all work together for the next thousand years, we’ll finally reach our goal! NASA has been tracking
SANTA BARBARA, California — Harris Corp. and L3 Technologies said June 21 that their merger has the regulatory approvals needed to close following a Justice Department decision. The Justice Department stipulated that Harris Corp. divest its night vision business for the merger to proceed. Harris Corp. and L3 Technologies are the sole suppliers of a
