Watch live: Falcon 9 test-firing imminent at Cape Canaveral
SpaceX is counting down to a static fire test of a Falcon 9 rocket on pad 40 at Cape Canaveral Space Force Station in Florida. The test-firing of the booster’s nine engines is in preparation for a launch with 54 more Starlink internet satellites as soon as Sunday night at 10:53 p.m. EDT (0253 GMT Monday).
DART Sees Asteroid Didymos for the First Time. In two Weeks, it'll Crash Into the Moon
NASA’s Double Asteroid Redirection Test (DART) mission is on its way to rendezvous with the double-asteroid Didymos. When it arrives on September 26th, DART will collide with Dimorphos – the 160-meter (525-foot) moonlet that orbits the main body – to evaluate the kinetic impact technique for the very first time. This proposed method of planetary defense consists of a spacecraft colliding with an asteroid to alter its orbit and prevent it from colliding with Earth. In July, DART took its first image of the double-asteroid, which NASA released earlier this week!

New Animation Shows how the Artemis Missions Will use the Lunar Gateway and a Starship to put Humans Back onto the Moon
A recent YouTube video made by YouTube account, Hazegrayart, combines awesome computer animation, great music, and crisp archived audio recordings to show how NASA’s future Lunar Gateway will function for the upcoming Artemis missions. The archived audio recordings encompass only about a third of the short four and a half minutes of video, with almost the entire length being filled with a gorgeous and relaxing soundtrack as the viewer is left fixated watching a slow and methodical ballet of spaceships come together at Gateway.
US will push other nations to abandon destructive anti-satellite tests, VP Harris says
The United States will soon ask other nations to follow its lead and abandon destructive, debris-spawning anti-satellite testing, Vice President Kamala Harris said.
Just 2,000 Years Ago, Betelgeuse Was Yellow, Not Red
Compared to the lifespan of stars, human lives are pretty short. Stars such as Betelgeuse (in Orion) live for millions of years. Others exist for billions of years. We (if we’re lucky) get maybe 100 years (more or less). So, to us, stars don’t appear to change much over our lifetimes, unless they blow up as supernovae. But, what about over the course of 20 or 30 successive lifetimes?

Insanely High-Resolution Images of the Sun Show its Chromosphere in Vivid Detail
New images of the Sun’s chromosphere – the lower region of the solar atmosphere — have been released, and to say they are ‘stellar’ is an understatement. Simply, they are stunning. The high-resolution images were taken with the now-fully-operational Daniel K. Inouye Solar Telescope, located on the summit of Haleakala, Maui, in Hawai‘i. Scientists say the new observatory — with its large 4-meter (13-ft) primary mirror — will enable a new era of solar science, and provide a leap forward in understanding the Sun and its impacts on our planet.
A Planet has Been Found Orbiting Two Stars
To date, 5,084 extrasolar planets have been confirmed in 3,811 planetary systems, with another 8,912 candidates awaiting confirmation. These discoveries have provided astronomers with a detailed sampling of the types of planets that exist in our Universe, ranging from gas giants several times the size of Jupiter to smaller, rocky bodies like Earth. So far, the vast majority of these have been discovered using indirect methods – like the Transit Method (Transit Photometry) and the Radial Velocity Method (Doppler Spectroscopy) – while the remainder has been detected using various other means.
