Science advances through data that don’t fit our current understanding. At least that was Thomas Kuhn’s theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome new data that challenges their understanding of how the universe works. A recent paper, available in pre-print on arXiv, using data from the James Webb Space Telescope (JWST) might just had found some data that can do that. It looked at an exoplanet around a millisecond pulsar and found its atmosphere is made up of almost entirely pure carbon.

Did NASA's Perseverance rover actually find evidence of life on Mars? We need to haul its samples home to find out, scientists say
We'll likely need to get Perseverance's samples to Earth to determine if they do indeed harbor evidence of Mars life —but the prospects of such a mission are cloudy at best.
Watch Russia launch 2.8 tons of cargo toward the ISS today
A Russian Progress freighter loaded with 2.8 tons of cargo will launch toward the International Space Station today (Sept. 11), and you can watch it live.

SpaceX buys $17 billion worth of satellite spectrum to beef up Starlink broadband service
SpaceX just bought $17 billion worth of satellite spectrum from debt-ridden operator EchoStar to enhance Starlink direct-to-cell phone connectivity.
This Wandering Black Hole Has Left Its Galactic Center
Our knowledge of black holes is incomplete. We know there are stellar mass black holes that are created when massive stars collapse on themselves at the end of their lives of fusion. We know that supermassive black holes reside in the hearts of galaxies and sometimes merge with each other. The fact that there are two other hypothetical types of black holes that may or may not exist—primordial black holes and intermediate mass black holes—illustrates how our understanding is lacking.

Scientists find evidence of flowing water on Ryugu’s ancient parent asteroid. 'It was a genuine surprise!'
Water may have flowed on the asteroid that birthed the space rock Ryugu a billion years after it formed, much later than previously thought, changing our perception of the early solar system.
Get ready to view Saturn at its closest point to Earth with $133 off this telescope from Celestron

Can we safely deflect a killer asteroid without making it worse? Only if we avoid the gravitational 'keyhole,' scientists say
If we slam an impactor into an asteroid in exactly the wrong spot, the space rock may pass through a "gravitational keyhole" that brings it to Earth.
Did NASA's Perseverance rover find evidence of ancient life on Mars? The plot thickens
NASA's Perseverance Mars rover has found yet more chemical signatures that could be associated with ancient Red Planet life — but we need to examine them here on Earth to fully understand them.
Gravitational wave detector confirms theories of Einstein and Hawking: 'This is the clearest view yet of the nature of black holes'
Celebrating 10 years since the first detection of gravitational waves coming from colliding black holes, LIGO has confirmed the predictions of the greatest minds in physics.

One Wrong Hit Could Send an Asteroid on a Collision Course with Earth
When a massive asteroid is hurtling toward Earth, the solution seems straightforward; smash a spacecraft into it and knock it off course. That’s exactly what NASA successfully did with the DART mission in 2022, they proved this concept works and dramatically altered the orbit of the asteroid Dimorphos. But new research reveals the chilling possibility that an asteroid hit in the wrong spot, and you might just be postponing the impact!
