Once hidden cellular structures emerge in fight against viruses New University of Arizona-led research has revealed the structure and function of one of bacteria’s latest strategies in the fight against viruses: a fleet of highly organized enzymes that provide a rapid immune response capable of quickly shredding the harmful DNA of viral invaders. phys.org Go to SourceRead More →
Here’s a Deepfake of Nixon Giving a Eulogy for the Apollo 11 Astronauts if Their Mission Failed It’s July 16th, 1969. The Apollo 11 crew have completed their training, and they’re in the Columbia Command Module atop a Saturn V rocket, to this day the most powerful rocket ever built. At 9:32 EDT the rocket lifts off, delivering the crew into Earth orbit 12 minutes after launch. After lift-off, the million spectators … Continue reading “Here’s a Deepfake of Nixon Giving a Eulogy for the Apollo 11 Astronauts if Their Mission Failed” The post Here’s a Deepfake of Nixon Giving a Eulogy for the ApolloRead More →
Astronomers Find a Galaxy Containing Three Supermassive Black Holes at the Center NGC 6240 is a puzzle to astronomers. For a long time, astronomers thought the galaxy is a result of a merger between two galaxies, and that merger is evident in the galaxy’s form: It has an unsettled appearance, with two nuclei and extensions and loops. NGC 6240 is about 400 million light years away, in … Continue reading “Astronomers Find a Galaxy Containing Three Supermassive Black Holes at the Center” The post Astronomers Find a Galaxy Containing Three Supermassive Black Holes at the Center appeared first on Universe Today.

NASA’s Webb to unveil the secrets of nearby dwarf galaxies In two separate studies using NASA’s upcoming James Webb Space Telescope, a team of astronomers will observe dwarf galaxy companions to the Milky Way and the nearby Andromeda galaxy. Studying these small companions will help scientists learn about galaxy formation and the properties of dark matter, a mysterious substance thought to account for approximately 85% of the matter in the universe. phys.org Go to SourceRead More →
Carbon soccer ball with extra proton probably most abundant form in space It is one of the most common forms of carbon in space: C60, a soccer ball-shaped carbon molecule, but one that has an extra proton attached to it. This is the conclusion of research carried out at Radboud University, which has succeeded for the very first time in measuring the absorption spectrum of this molecule. Such knowledge could ultimately help us to learn more about the formation of planets. The researchers will publish their findings on November 25th in Nature Astronomy. phys.org Go to SourceRead More →
Probing exoplanet atmospheres could reveal telltale signatures of life It may be that life is lurking out there on other planets. But stuck here on Earth, how can we ever know for sure? A good place to start is by looking for the compounds on other worlds that are known to be the key ingredients of life as we know it. phys.org Go to SourceRead More →
Planets around a black hole? Calculations show possibility of bizarre worlds Theoreticians in two fields defied the received wisdom that planets only orbit stars like the sun. They proposed the possibility of thousands of planets around a supermassive black hole. phys.org Go to SourceRead More →

New Satellites Will Tell Us Exactly how Quickly the Oceans are Rising One of the clearest signs of global warming, unless you live next to a glacier, are rising oceans. Now a joint mission involving the US and European countries is launching a pair of satellites to monitor the rising sea levels. The two satellites will monitor the oceans until 2030. There’s more to rising oceans than … Continue reading “New Satellites Will Tell Us Exactly how Quickly the Oceans are Rising” The post New Satellites Will Tell Us Exactly how Quickly the Oceans are Rising appeared first on Universe Today.

Aquatic Rover Drives on the Underside of the Ice in Antarctica Not all rovers are designed to roam around on the surface of other worlds like Mars. One rover, at least, is aquatic; a necessary development if we’re going to explore Enceladus, Europa, and the Solar System’s other watery worlds. This rover is called the Buoyant Rover for Under-Ice Exploration, or BRUIE. This is not a … Continue reading “Aquatic Rover Drives on the Underside of the Ice in Antarctica” The post Aquatic Rover Drives on the Underside of the Ice in Antarctica appeared first on Universe Today.

Chemistry in the turbulent interstellar medium Over 200 molecules have been discovered in space, some (like Buckminsterfullerene) very complex with carbon atoms. Besides being intrinsically interesting, these molecules radiate away heat, helping giant clouds of interstellar material cool and contract to form new stars. Moreover, astronomers use the radiation from these molecules to study the local conditions, for example, as planets form in disks around young stars. phys.org Go to SourceRead More →
