Summer officially kicks off in the Northern Hemisphere today (June 21), marking the longest day of the year. During the June solstice (or summer solstice), the sun reaches its highest and northernmost points in the sky. Here's how it works.
NASA's Artemis 1 moon mission completed a crucial preflight milestone Monday (June 20), wrapping up a two-day set of tests known as a wet dress rehearsal.
Those tests included fueling up Artemis 1's huge Space Launch System megarocket and performing a simulated countdown that took the vehicle and NASA's Orion capsule through most of the progressions they would endure on launch day before engine ignition.
NASA is scheduled to release the first images taken by the James Webb Space Telescope on July 12, 2022.
They'll mark the beginning of the next era in astronomy as Webb — the largest space telescope ever built — begins collecting scientific data that will help answer questions about the earliest moments of the universe and allow astronomers to study exoplanets in greater detail than ever before. But it has taken nearly eight months of travel, setup, te

planned reboost maneuver of the International Space Station ended after just 5 seconds for reasons currently unknown.
Cargo ships docked to the International Space Station regularly fire their thrusters in short bursts to keep the orbiting laboratory at its cruising altitude. Typically, these vehicles are Russian Progress capsules, but on Monday (June 20), a Northrop Grumman Cygnus vehicle was scheduled to complete a five-minute burn to evaluate whether the capsule is ready to take this duty on regularly.
China plans to haul Mars samples to Earth in 2031, two years before NASA and the European Space Agency aim to do so, according to media reports.
The target date was announced in a Monday (June 20) presentation(opens in new tab) by Sun Zezhou, chief designer of the Tianwen 1 Mars orbiter and rover mission that arrived at the Red Planet in February 2021.
A piece of space junk from a Russian anti-satellite weapons test forced the International Space Station to maneuver to avoid the orbital debris on June 16.
Russia's space agency Roscosmos used an uncrewed Progress 81 cargo ship docked at the International Space Station to move the orbiting lab clear of a piece of space debris from the Russian satellite Cosmos 1408
Thousands of distant, primordial galaxies in different shapes and sizes glow in infrared light in a newly released image from the Hubble Space Telescope.
The oldest galaxies are about 13 billion years old, dating from just a few hundred million years after the Big Bang. By looking at those galaxies in ultraviolet light, scientists can discover what chemicals lie inside those galaxies — information that is key to understanding how galaxies form and evolve. But there's a problem with this method: That primordial ultraviolet light gets absorbed before it can reach us.
A raging wildfire is "mostly holding" at Kitt Peak National Observatory, which remains too dangerous for astronomers to verify how much of the area was damaged, officials said in an update Monday.
Although initial evaluations suggest that all the telescope domes remain standing, the Arizona facility remains an "active fire fighting" area, with aerial firefighting efforts continuing by planes and helicopters over both the observatory and neighboring communities, officials from the National Science Foundation's National Optical-Infrared Astronomy Research Laboratory, which runs the observatory, said in a statement.
SpaceX just completed a remarkable spaceflight tripleheader.
A two-stage Falcon 9 rocket launched from Florida's Cape Canaveral Space Force Station on Sunday (June 19) at 12:27 a.m. EDT (0427 GMT), carrying a communications satellite for the Louisiana-based company Globalstar to orbit. It was the third mission for SpaceX in just over 36 hours.
The companies have written a joint letter to the U.S. Federal Communications Commission (FCC), declaring harmony in low Earth orbit (LEO) for spectrum coordination between their respective current and next generation broadband constellations.
In the letter, which is dated June 13, SpaceX and OneWeb request that the FCC disregard previously filed dissenting comments regarding spectrum coordination in LEO.

Located at the Devasthal Observatory in India's Himalayas, at an elevation of 8,038 feet (2,450 meters), the four-meter International Liquid Mirror Telescope (ILMT) is the first liquid telescope to be built specifically for astronomy.
Most telescopes use glass mirrors, but as the ILMT's name suggests, its mirror is made from a thin layer of liquid mercury that floats on 10 microns of compressed air and rotates every eight seconds.
Is that Buzz Lightyear to the rescue? NASA's Z-1 spacesuit prototype, released a decade ago, looks just like the iconic space ranger's extraterrestrial duds in the Toy Story franchise.
While the project is no longer happening, contractors do have access to its development history to create their own future spacesuits for agency needs, including moon missions.
Disney/Pixar's highly-anticipated "Lightyear" arrived in theaters this weekend, and where this prequel spin-off of the iconic "Toy Story" empire should have been an electrifying slam dunk, the event film comes across as a stiff piece of corporate entertainment that lacks heart and magic.
If you've seen the trailers for Disney's "Lightyear," you've seen its apparent time travel plotline. But is time travel something we could really achieve?
