Imagine you are singing in a choir. You are doing your best, just like everybody else. Suddenly, somebody turns to you and points out that you are not singing the right note. If you are told off in a harsh way, you may feel bad about it, and if this happens too often you might not only feel upset about the choir but might even leave it for good. Eventually, the whole choir could end if everybody just leaves.
SpaceX's Dragon capsules have spent more time in orbit, and launched toward the International Space Station more often, than NASA's space shuttle fleet.
Skywatchers can see the moon meet up with Saturn in the early hours of June 10 as the two bodies make a close approach in the night sky.
Astronauts on NASA's Artemis moon missions might look for signs of life in shadowed polar craters — life that could have traveled with people from Earth.
An astronaut who helped assemble the International Space Station is now behind a series of space building projects that are on a very different scale. Naoko Yamazaki advised on Nanoblock's new kits.
Now it's Venus's turn to pass the Beehive, with Leo looming over. The Summer Triangle lofts high. And the supernova in M101, near the Big Dipper, remains 11th magnitude.

Our Sun continues to demonstrate its awesome power in a breathtaking collection of recent images taken by the U.S. National Science Foundation’s (NSF’s) Daniel Inouye Solar Telescope, aka Inouye Solar Telescope, which is the world’s largest and most powerful ground-based solar telescope. These images, taken by one of Inouye’s first-generation instruments, the Visible-Broadband Imager (VBI), show our Sun in incredible, up-close detail.
Star formation is one of the oldest processes in the Universe. In the Milky Way and most other galaxies, it unfolds in cold, dark creches of gas and dust. Astronomers study sites of star formation to understand the process. Even though they know much about it, some aspects remain mysterious. That’s particularly true for the “Nessie Nebula” in the constellation Vulpecula. An international team led by astronomer James Jackson studies the nebula and its embedded star-birth regions. They found that it experienced a domino effect called “triggered star formation.”
A monstrous galactic cluster is devouring another group of galaxies whole, causing it to emit a 1.5 million light-year-long trail of hot gas from its rear — the largest of this type ever seen.
The James Webb Space Telescope has discovered hundreds of galaxies that existed when the universe was less than 600 million years old.
The Pentagon has confirmed it is buying SpaceX's Starlink broadband services to provide communications in Ukraine.

Virgin Orbit, the satellite launch company founded by British billionaire Richard Branson, has permanently ceased operations, just a few months after a major mission failure in January and at a time when it was already facing financial headwinds.
Smoke from Canadian wildfires has obscured the view of Earth-monitoring satellites like GOES-16 and the PlanetScope constellation.
Aerospace giant Boeing faces a federal lawsuit accusing it of intellectual property theft and misuse of critical components involved in assembling NASA's Artemis moon rocket.
Long spaceflights can cause astronauts' ventricles — cavities in the brain that hold cerebrospinal fluid — to enlarge by up to 25%. And it apparently takes years for the swelling to go down.
Get up to speed on all the Transformers movies released so far, both in chronological and release order, with our comprehensive guide.
Night Sky is a stargazing app built on ease of use and a sense of wonder.
California residents will be glad to know their reservoirs are nearly full again after years of drought. New satellite photos show the levels of Shasta Lake, California’s largest reservoir, going from 31% capacity last November to nearly 100% in May 2023. The reservoir was filled with heavy rains and a significant mountain snowpack that melted into the nearby rivers.
