Live coverage: Japan to launch new X-ray space telescope
A next-generation X-ray space telescope and an experimental lunar lander are poised for launch Sunday from Japan. An H-2A rocket is scheduled to liftoff from the Tanegashima Space Center at 8:26 p.m. EDT (9:26 a.m. local time / 0026 UTC).
The Early Universe Should Be Awash in Active Galaxies, but JWST Isn't Finding Them
For decades the most distant objects we could see were quasars. We now know they are powerful active black holes. Active galactic nuclei so distant that they resemble star-like points of light. It tells us that supermassive black holes in the early Universe can be powerful monsters that drive the evolution of their galaxies. We had thought most early supermassive black holes went through such an active phase, but a new study suggests most supermassive black holes don’t.

Meet Crew 7: A truly international space mission
Dragon Endurance features crew members representing four different nations. The mission is commanded by NASA astronaut Jasmin Moghbeli. The pilot is the European Space Agency’s Andreas Mogensen from Denmark. Mission specialists are Japanese astronaut Satoshi Furukawa and Russian cosmonaut Konstantin Borisov.
Contrails: What are they and how do they form?
Condensation trails, or contrails, are long, thin clouds that can form behind airplanes at cruising altitude. They are created by jet engines.
Ukraine's famed space sector is teetering on the brink, and Russian missiles aren't the main cause
Ukraine's former space chief thinks lost international collaborations are causing even greater harm to his nation's space sector than Russian missile strikes.
40th Rocket Lab Mission, “We Love The Nightlife”, Launches From New Zealand with Reused Engine
Private space company, Rocket Lab, launched its 40th Electron mission on their lauded Electron rocket, dubbed “We Love The Nightlife”, on August 24th at 11:45am New Zealand Standard Time (August 23rd at 7:45pm EST), which also marks the 7th launch of 2023, all successful. The purpose of the mission was to deliver the next-generation Acadia satellite for Capella Space to a circular orbit above the Earth at 640 km (400 miles), which was executed flawlessly. Acadia is part of Capella’s synthetic aperture radar (SAR) constellation and is the first of four Acadia satellites that Rocket is currently contracted to launch for Capella.

Pulsars Detected the Background Gravitational Hum of the Universe. Now Can They Detect Single Mergers?
Current gravitational wave observatories have two significant limitations. The first is that they can only observe powerful gravitational bursts such as the mergers of black holes and neutron stars. The second is that they can only observe these mergers for wavelengths on the order of hundreds to thousands of kilometers. This means we can only observe stellar mass mergers. Of course, there’s a lot of interesting gravitational astronomy going on at other wavelengths and noise levels, which has motivated astronomers to get clever. One of these clever ideas is to use pulsars as a telescope.
