Here we go again! Controversial paper questions whether interstellar visitor 3I/ATLAS is 'possibly hostile' alien tech in disguise

Space.com - Tue, 07/29/2025 - 1:00pm
A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

Is gravity a new type of force that arises from cosmic entropy?

New Scientist Space - Cosmology - Tue, 07/29/2025 - 12:00pm
Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency to get more disordered. Now this idea might finally be testable

NASA Drop Test Supports Safer Air Taxi Designs

NASA Image of the Day - Tue, 07/29/2025 - 11:37am
An aircraft body modeled after an air taxi with weighted test dummies inside is being prepared for a drop test by researchers at NASA’s Langley Research Center in Hampton, Virginia. The test was completed June 26 at Langley’s Landing and Impact Research Facility. The aircraft was dropped from a tall steel structure, known as a gantry, after being hoisted about 35 feet in the air by cables. NASA researchers are investigating aircraft materials that best absorb impact forces in a crash.

A New Lunar Far Side Radio Telescope Is Ready For Testing

Universe Today - Tue, 07/29/2025 - 7:43am

We’ve been talking about sending a radio telescope to the far side of the Moon for awhile now. Now that reality is one step closer with the completion of the design and construction phase of the Lunar Surface Electromagnetics Experiment-Night (LuSEE-Night) radio telescope project. This milestone marks a major step in the development of the system, which is planned to launch on a lunar lander in 2026.

JWST Reveals Four Distinct CO₂ Types on Saturn’s Moons

Universe Today - Tue, 07/29/2025 - 7:43am

What can carbon dioxide (CO₂) on Saturn’s moons teach scientists about their formation and evolution? This is what a recent study submitted to The Planetary Science Journal hopes to address as a team of researchers investigated the different types of CO₂ that exist on several of Saturn’s mid-sized moons. This study has the potential to help scientists better understand the existence of CO₂ on planetary bodies and what this could mean for their formation and evolution, and potentially whether they could possess life as we know it.

Primordial Black Holes Could Act As Seeds For Quasars

Universe Today - Tue, 07/29/2025 - 7:43am

Plenty of groups have been theorizing about Primordial Black Holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had other roles to play in the early universe. According to a recent draft paper released on arXiv by Jeremy Mould and Adam Batten of Swinburne University, one of those roles could be as the seeds that eventually form both quasars and radio galaxies.

Lunar Dust Mitigation Requires Collaboration And Lots of Tests

Universe Today - Tue, 07/29/2025 - 7:43am

Collaboration has always been a hallmark of space research. Experts in different disciplines come together to work towards a common goal, and many times achieve that. One of the current goals of space exploration is long-term settlement of the Moon, and in order to achieve that goal, engineers and astronauts will have to deal with one of the thorniest problems on that otherworldly body - dust. Lunar dust is much harder to deal with that Earth’s equivalent, as it is sharp, charged, and sticks to everything, including biological tissue such as lungs, and even relatively smooth surfaces like glass. Several research groups are working on mitigation techniques that can deal with lunar dust, but a new cross-collaborative group from the University of Central Florida is developing a coating, testing it, and simulating all in one project, with the hopes that someday their solution will make it easier for astronauts to explore our nearest neighbor.

New Findings Indicate that the Origin of Life Started in Space

Universe Today - Tue, 07/29/2025 - 7:43am

In the young V883 Orionis system, ALMA observations have revealed signatures of complex organic compounds such as ethylene glycol and glycolonitrile – potential precursors to amino acids, DNA, and RNA. These findings indicate that the building blocks of life may not be limited to local conditions but could form widely throughout the Universe under suitable circumstances.

Mars' Seasonal Frost Could Briefly Host Liquid Water

Universe Today - Tue, 07/29/2025 - 7:43am

What can brine (extra salty) water teach scientists about finding past, or even present, life on Mars? This is what a recent study published in Communications Earth & Environment hopes to address as a researcher from the University of Arkansas investigated the formation of brines using 50-year-old data. This study has the potential to help researchers better understand how past data can be used to gain greater insights on the formation and evolution of surface brines on the surface of Mars.
