SpaceX's Starship megarocket tends to put on a show, and its latest test flight was no exception. See some gorgeous photos of the vehicle in space on Flight 9.

Houston company Axiom Space's Ax-4 astronaut launch to the International Space Statio has been delayed by two days, to June 10.
In honor of the live-action 'Lilo & Stitch', we look back at 12 extra-terrestrials who came in peace.
Astronomy has lost one of its most assiduous calculators of eclipses with the passing of astronomer Fred Espenak, known widely as "Mr. Eclipse."
Chinese rocket startup Space Epoch put on a show recently, with a demonstration test launch of their reusable Yanxinghe-1 rocket booster.
The 2025 Atlantic Hurricane season expected to be busier than normal, according to NOAA forecasters.
Supermassive black holes could act as natural particle accelerators, helping humanity investigate dark matter.

New research suggests there may be a narrow window of possibility for life to persist on the icy moons of the outer solar system.
A SpaceX Falcon 9 rocket launched 23 satellites for the company's Starlink constellation from Cape Canaveral, Florida on June 3, 2025.
Auroras may be visible from Alaska to Oregon as geomagnetic storm conditions start to wane.
In-orbit servicing and refueling could help curb the environmental harm done by the space industry. But will operators subscribe to the greener business model? The jury is out.
A newly designed, AI-powered program could solve the puzzle of binary stars in mere seconds using a common laptop, a process that currently takes supercomputer clusters weeks.
Japanese lunar exploration company ispace will attempt to land its RESILIENCE spacecraft on the Moon no earlier than 5 June (CEST) 2025.
On the surface (you're welcome for the joke), Venus is not even close to being hospitable to life. But that's not the end of the story.
Mars is by far the most Earth-like planet in the solar system…but that’s not saying much.
Mars has received considerable attention in the past few decades, thanks to the many robotic missions exploring it to learn more about its past. NASA and China plan to send astronauts/taikonauts there in the coming decades, and commercial space companies like SpaceX hope to send passengers there sooner. This presents several significant challenges, one of the greatest being the lengthy transit times involved. Using conventional propulsion and low-energy trajectories, it takes 6 to 9 months for crewed spacecraft to reach Mars.
The U.S. Astronaut Hall of Fame just held its annual induction ceremony, but one of this year's two honorees could not attend for a reason unique to all past enshrinements.
Mars' core formed within just a few million years, scientists say compared to the hundreds of millions or even billions of years that it took for Earth's core to form — it also might smell like rotten eggs.
The challenge in the search for habitable worlds is clear. We need to be able to identify habitable worlds and distinguish between biotic and abiotic processes. Ideally, scientists would do this on entire populations of exoplanets rather than on a case-by-case basis. Exoplanets' natural thermostats might provide a way of doing this.
