El Nino is officially here and may cause temperature spikes and major weather events, scientists warn
The World Meteorological Organization has declared the onset of El Niño conditions in the tropical Pacific, leading to surging temperatures and disruptive weather that could threaten lives.
The Early Universe Ran in Slow Motion
Time is relative, as they say, particularly for mid-day meals. As special relativity shows, the measure of any two clocks depends on their motion relative to each other. The greater their relative speed, the slower each clock is relative to each other. So, since we see distant galaxies speeding away from us, we should also see time move more slowly. Right?
Time appeared to move 5 times more slowly in 1st billion years after Big Bang, quasar 'clocks' reveal
Time dilation, brought about by the relativistic expansion of space, has resulted in the observed slowing of 'clocks' in the early universe.
'Terminator 3': Average movie, fantastic ending
Twenty years on, 'Rise of the Machines' powerful and bleak conclusion remains one of the highlights of the killer cyborg franchise.
A 'double punch' of solar storms could smash into Earth and spark widespread auroras this week
As the U.S. celebrated July 4, the sun hosted its own fireworks display in the form of a coronal mass ejection "double punch" that NASA predicts could strike Earth on Friday (July 7).
Mars helicopter calls home after long communications blackout
NASA’s Ingenuity Mars Helicopter’s navigation camera captured the rotorcraft in shadow during its 52nd flight on April 26, 2023. This image was finally received after Ingenuity was out of communication for 63 days. Image: NASA/JPL-Caltech.
NASA engineers are prepping the miniature Mars helicopter Ingenuity for its 53rd flight across the surface of the Red Planet after re-establishing contact following a two-month radio blackout.
Secret Invasion season 1 episode 3 review: Nick Fury and Talos go on the offensive
Episode 3 of Marvel's Secret Invasion doesn't pack a lot of character work, focusing instead on ramping up the plot and delivering shocking twists.

The Outer Worlds is a warning of the corporate space age we're barreling towards
Obsidian's dark satire is a warning that leaving billionaires in charge of our expansion to the stars might not be the best idea, which is a shame because it's exactly what we're doing.
Alien's-eye view of the Milky Way: Our galaxy is unusual but not unique
Astronomers have now deduced what alien scientists might see when they gaze at the Milky Way from afar. Our home galaxy is unusual but not unique, at least when it comes to chemistry.
Satellites uncover 'invisible' auroras glowing in infrared in Earth's atmosphere
Scientists have observed an aurora glimmering in infrared light, created by the interaction of energetic cosmic particles and carbon dioxide in Earth's atmosphere.
ESA's Euclid Mission is Off to Explore the Dark Universe
On Saturday, July 1st (Canada Day!), the ESA’s Euclid space telescope lifted off from Cape Canaveral in Florida. This next-generation astrophysics mission will spend the next few weeks flying to the Earth-Sun L2 Lagrange Point, where it will spend the next six years observing one-third of the sky. During that time, Euclid will observe billions of galaxies to a distance of 10 billion light-years, leading to the most extensive 3D map of the Universe ever created. This map will help astronomers and cosmologists resolve the lingering mystery of Dark Matter and Dark Energy (DM & DE).
James Webb is a GO for Cycle 2 Observations!
The James Webb Space Telescope (JWST) has accomplished some amazing things during its first year of operations! In addition to taking the most detailed and breathtaking images ever of iconic celestial objects, Webb completed its first deep field campaign, turned its infrared optics on Mars and Jupiter, obtained spectra directly from an exoplanet’s atmosphere, blocked out the light of a star to reveal the debris disk orbiting it, detected its first exoplanet, and spotted some of the earliest galaxies in the Universe – those that existed at Cosmic Dawn.
The James Webb Space Telescope spots the wreckage of a cosmic clash of the Titans (image)
The James Webb Space Telescope has spied a distant galaxy that represents the wreckage of a titanic collision between two galaxies 500 million years ago.
NASA's VIPER Rover's First Moments on the Moon Might Be its Most Terrifying
NASA is building its first-ever robotic lunar rover. Named VIPER (Volatiles Investigating Polar Exploration Rover), the rover is set for launch in late 2024. But the terrain it will find when it reaches the Moon is impossible to predict. A series of tests carried out this spring are helping engineers understand the rover’s limits, and will ensure that VIPER can disembark from its lander even on extremely uneven terrain.
The UK's ODIN Space just aced its 1st space junk tracking system test in orbit
ODIN Space's demonstration team confirmed their new debris sensor successfully recorded acoustic data during its recent on-orbit test, bringing micro-space debris tracking a step closer to reality.
"Shooting stars" seen raining down on the sun for the first time (images)
New observations of the sun have revealed never-before-seen meteor-like fireballs raining down as shooting stars on the surface of the sun.
Tour the mock Mars habitat where 4 NASA analog astronauts will spend the next year (video)
This video from NASA shows just how much space the four CHAPEA crew members will be sharing during their year-long mission.
Gravitational Waves Can Be Gravitationally Lensed, and This Could Provide Another Way to Measure the Expansion of the Universe
Gravitational waves don’t travel through space and time. They are ripples in the fabric of spacetime itself. This is why they are so difficult to detect. We can only observe them by closely watching how objects bent and stretched within spacetime. But despite their oddness, gravitational waves behave in many of the same ways as light, and astronomers can use that fact to study cosmic expansion.
