Giant Meteor Impacts Might Have Triggered Early Earth’s Plate Tectonics A new study by an Australian-US team has found that a large impact that happened ca. 3.2 billion years ago could be what started Earth’s tectonics activity, which could be crucial to why Earth is able to support life.

Astronomers Are About to Detect the Light from the Very First Stars in the Universe A team of scientists working with the Murchison Widefield Array (WMA) radio telescope are trying to find the signal from the Universe’s first stars. Those first stars formed after the Universe’s Dark Ages. To find their first light, the researchers are looking for the signal from neutral hydrogen, the gas that dominated the Universe after … Continue reading “Astronomers Are About to Detect the Light from the Very First Stars in the Universe” The post Astronomers Are About to Detect the Light from the Very First Stars in the UniverseRead More →

When Martian Storms Really Get Going, they Create Towers of Dust 80 Kilometers High When a huge dust storm on Mars—like the one in 2018—reaches its full power, it can turn into a globe-bestriding colossus. This happens regularly on Mars, and these storms usually start out as a series of smaller, runaway storms. NASA scientists say that these storms can spawn massive towers of Martian dust that reach 80 … Continue reading “When Martian Storms Really Get Going, they Create Towers of Dust 80 Kilometers High” The post When Martian Storms Really Get Going, they Create Towers of Dust 80 Kilometers High appeared first onRead More →

NASA Supercomputer Simulates the Weather on Mars The Martian atmosphere is a lot different than Earth’s. It’s over 95% carbon dioxide, and contains only trace amounts of oxygen and water vapor. But that trace amount of water vapor still plays a pronounced role in the climate. NASA is very interested in Mars’ atmosphere, weather, and climate. The more they know about Mars, … Continue reading “NASA Supercomputer Simulates the Weather on Mars” The post NASA Supercomputer Simulates the Weather on Mars appeared first on Universe Today.

Finally! Scientists Find a Place on Earth with Liquid Water But No Life In recent years research into extremophiles has captured the interest of astrobiologists. The discovery of lifeforms in some of Earth’s most extreme environments has helped shape our thinking about extraterrestrial life. Life on other worlds may not need the kind of temperate, balanced environment that most life on Earth is adapted to. The search for … Continue reading “Finally!

A Fifth Fundamental Force Could Really Exist, But We Haven’t Found It Yet The universe is governed by four fundamental forces: gravity, electromagnetism, and the strong and weak nuclear forces. These forces drive the motion and behavior of everything we see around us. At least that’s what we think. But over the past several years there’s been increasing evidence of a fifth fundamental force. New research hasn’t discovered … Continue reading “A Fifth Fundamental Force Could Really Exist, But We Haven’t Found It Yet” The post A Fifth Fundamental Force Could Really Exist, But We Haven’t Found It Yet appeared first on Universe Today.

Building Space Telescopes… In Space When it comes to telescopes, bigger is better. That’s true down here on Earth, and it’s especially true out in space. As astronomers and engineers design the next generation of giant space telescopes, they’re running up against the limits of current launch providers. There are only so many ways you can fold a huge telescope … Continue reading “Building Space Telescopes… In Space” The post Building Space Telescopes… In Space appeared first on Universe Today.

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.

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.
