It's apparently never too early to start the MCU hype machine rolling!
One of the most consequential events—maybe the most consequential one throughout all of Earth's long, 4.5 billion year history—was the Great Oxygenation Event (GOE). When photosynthetic cyanobacteria arose on Earth, they released oxygen as a metabolic byproduct. During the GOE, which began around 2.3 billion years ago, free oxygen began to slowly accumulate in the atmosphere.
A recent string of cyberattacks against the European Space Agency is just the tip of the iceberg, a researcher said, claiming that email credentials of ESA employees are regularly leaked online.
The shadow nebula LDN 1245 is located in the constellation Cassiopeia.
One of the most stubborn issues in cosmology today concerns the Universe's rate of expansion. Scientists know it's expanding, but defining the rate of that expansion is challenging. The rate of expansion is called the Hubble Constant, after American astronomer Edwin Hubble, who discovered that the Universe is expanding in the 1920s.
Back in the earlier days of the internet, there was a viral video from a creator called Bill Wurtz called “the history of the entire world, i guess” which spawned a number of memorable memes, some of which are still in use to this day. One of those was a clip from the video where Wurtz states “The Sun is a deadly laser.” Apparently, that was more true than even he knew, as a new paper from Georgios Tsirvouils of the Luleå University of Technology in Sweden and his co-authors have shown experimental evidence that the Sun’s laser-like radiation is likely responsible for the death of a vast majority of closely-orbiting asteroids.
"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?"
The image shows just how large and devastating these events can be.
The noisy fandom is about to have a field day with Star Trek: Starfleet Academy.
Space school is officially in session and here's your center seat invitation!
NASA leaders said the Crew-11 mission's astronaut medical evacuation shows how the agency is prepared to handle the unexpected.
The DJI Neo 2 delivers improved image quality alongside Omnidirectional Obstacle Avoidance and many other new and impressive features.
When the Sun erupts in its most violent flares, it doesn’t just hurl plasma and particles into space. These explosions also generate intense bursts of gamma radiation, the most energetic form of light in the universe. Solar physicists have detected these gamma ray signals for decades, yet the precise mechanism producing them remained frustratingly elusive. Now researchers at the New Jersey Institute of Technology have pinpointed the source.
"This is a structure we've never seen before, so it could be a new class of dark object."

Four space station crewmates undocked and plunged back to Earth Thursday, safely splashing down in the Pacific Ocean off the California coast six days after NASA ordered them home early because of a medical issue.
Right now, as you read this sentence, roughly a trillion neutrinos are passing straight through your body. They slip through flesh and bone and even brain without leaving a trace, streaming through the entire planet as if it weren’t there at all. These ghost particles have earned their name through spectacular elusiveness, interacting so rarely with ordinary matter that detecting even one requires enormous underground detectors and considerable patience.
The four astronauts of SpaceX's Crew-11 mission splashed down safely today (Jan. 15) after the first-ever medical evacuation of the International Space Station.
After more than 10 years in orbit, the first Copernicus Sentinel-2 satellite, Sentinel-2A, is still finding new ways to contribute to Earth observation. With its younger siblings, Sentinel-2B and Sentinel-2C, now leading the mission’s core task of delivering high-resolution, ‘camera-like’ images of Earth’s surface, the European Space Agency is pushing Sentinel-2A beyond its original remit.
2026 sees Starfleet Academy and a new season of Strange New Worlds enter the Star Trek universe, so now is the time to save big on Paramount Plus and a VPN.
"If they were purely made up of stars, they would be the densest galaxies in the universe."

The SpaceX Crew-11 mission is coming to a close with the crew preparing to depart the International Space Station Wednesday afternoon and splashdown off the coast of California in the predawn hours on Thursday.
