It's Time to Build a Space Telescope Interferometer. This Could be the First Step

Universe Today Feed - Wed, 04/16/2025 - 11:51am

The dream of finding life on an alien Earth-like world is hampered by a number of technical challenges. Not the least of which is that Earth is dwarfed by the size and brightness of the Sun. We might be able to discover evidence of life by studying the molecular spectra of a planet's atmosphere as it passes in front of the star, but those results might be inconclusive. The way to be certain is to observe the planet directly, but that would take a space telescope with a mirror 3–4 times that of Webb.

The hairtail fish

Why Evolution is True Feed - Wed, 04/16/2025 - 11:45am

Enjopy this one-minute video of a largehead hairtail (Trichiurus lepturus), the “liquid metal fish”, also called the “beltfish”.  As you can see, it’s a predator, and it’s gone some set of choppers. Its metallic color apparently camouflages it from prey. And look at that dorsal fin!

Some info from Wikipedia (their bolding):

The largehead hairtail (Trichiurus lepturus) or beltfish is a member of the cutlassfish family, Trichiuridae. This common to abundant species is found in tropical and temperate oceans throughout the world. The taxonomy is not fully resolved, and the Atlantic, East Pacific and Northwest Pacific populations are also known as Atlantic cutlassfishPacific cutlassfish and Japanese cutlassfish, respectively. This predatory, elongated fish supports major fisheries.

I wish they wouldn’t hold these things so long out of the water, as it makes them suffer. And I hope even more that they didn’t kill it.

Scientists find evidence that overturns theories of the origin of water on Earth

Space and time from Science Daily Feed - Wed, 04/16/2025 - 10:59am
Researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early Earth to understand the origin of hydrogen on our planet. The research team demonstrated that the material which built our planet was far richer in hydrogen than previously thought. The findings support the theory that the formation of habitable conditions on Earth did not rely on asteroids hitting the Earth.

The most distant twin of the Milky Way ever observed

Space and time from Science Daily Feed - Wed, 04/16/2025 - 10:57am
An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang and already shows a remarkably mature structure, with a central old bulge, a large star-forming disk, and well-defined spiral arms. The discovery was made using data from the James Webb Space Telescope (JWST) and offers important insights into how galaxies can form and evolve so rapidly in the early Universe.

Researchers introduce a brand-new method to detect gunshot residue at the crime scene

Matter and energy from Science Daily Feed - Wed, 04/16/2025 - 10:57am
Crime scene investigation may soon become significantly more accurate and efficient thanks to a new method for detecting gunshot residues. Researchers have developed the technique that converts lead particles found in gunshot residue into a light-emitting semiconductor. The method is faster, more sensitive, and easier to use than current alternatives. Forensic experts at the Amsterdam police force are already testing it in actual crime scene investigations.
