A delicate tracery of dust and bright star clusters threads across this image from the NASA/ESA/CSA James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.
A new mosaic of Mars marks 20 years since the launch of ESA's Mars Express, and reveals the planet’s colour and composition in spectacular detail.
Venus shining in the dusk says goodbye to Pollux, hello to Mars. . . which is busy crossing the Beehive Cluster. Arcturus stands straight over Spica after dark, and Kochab stands straight over Polaris, it's that time of year.

"It is not darkness that unites us, not the cold distance of space, but the offering of water..." Those words, by U.S. Poet Laureate Ada Limón, are part of an ode flying on NASA's Europa Clipper.
Boeing is standing down for the first-ever crewed launch of its Starliner capsule for NASA due to safety issues with the spacecraft's parachutes and wiring.

Boeing and NASA officials said Thursday the first launch of astronauts on Boeing’s delay-prone Starliner crew capsule won’t happen in July after engineers recently discovered a problem with the spacecraft’s parachute system and identified flammable tape around wiring harnesses inside the vehicle.
It’s almost impossible to over-emphasize the primal, raging, natural power of a star. Our Sun may appear benign in simple observations, but with the advanced scientific instruments at our disposal in modern times, we know differently. In observations outside the narrow band of light our eyes can see, the Sun appears as an enraged, infuriated sphere, occasionally hurling huge jets of plasma into space, some of which slam into Earth.
Astronomers discovered two mini-Neptunes and a third potential exoplanet in the final data sent home by NASA's Kepler space telescope just before it was decommissioned in late 2018.
When astronomers discovered WASP-18b in 2009, they uncovered one of the most unusual planets ever found. It’s ten times as massive as Jupiter is, it’s tidally locked to its Sun-like star, and it completes an orbit in less than one Earth day, about 23 hours.
Anyone who’s ever lived along a coastline or been at sea knows the effects of tsunamis. And, they appreciate all the early warning they can get if one’s on the way. Now, NASA’s GNSS Upper Atmospheric Real-time Disaster and Alert Network (GUARDIAN) is using global navigation systems to measure the effect these ocean disturbances have on our atmosphere. The system’s measurements could provide a very effective early warning tool for people to get to higher ground in the path of a tsunami.
The James Webb Space Telescope spotted water in the atmosphere of the exoplanet WASP-18 b, which reaches nearly 5,000 degrees Fahrenheit (2,700 degrees Celsius).

An attempt to place a small North Korean military spy satellite into orbit May 30 failed a few minutes after liftoff, five days after South Korea successfully launched the country’s homegrown Nuri rocket with several technology demonstration and scientific research spacecraft.
How do you weigh a galaxy? It’s an astronomical challenge, particularly if it’s the galaxy you call home. It turns out there are several ways to get a handle on the mass of the Milky Way, and a recent study summarizes these methods to present the best value.
Telltale Games is reviving The Expanse with a prequel game series, and we’ve played the first episode.
One of the brightest stars in the night sky has been getting oddly brighter, prompting speculations that it might soon explode in a supernova. Can we really expect that celestial spectacle?
