LISA Could Double as an Asteroid Scale

One of the hardest things to calculate for an asteroid is its mass - but it is such a critical feature. It determines how much of an impact it would have if it hits something, or how many resources are potentially available on it. But to accurately measure it we typically use optical sensing and a guesstimate of its density based on its spectral profile. A new paper suggests a completely novel way to use the Laser Interferometer Space Antenna (LISA) flagship mission to potentially provide highly accurate mass calculations for nearby asteroids without any change in hardware.



The Little Red Dots That Turned Out to Be Black Holes in Disguise

For three years they've been one of the strangest puzzles in astronomy. Tiny, mysterious red dots scattered across the early universe, so abundant and so bright that some researchers wondered if they had "broken" cosmology itself. Now the James Webb Space Telescope has captured the most detailed look yet at one of them, and the answer it reveals is as exotic as the name suggests: a star sized object that is, in fact, a black hole wearing a disguise.



FAST Finds a Pulsar in an Almost Flawless Circular Orbit

Somewhere in the plane of the Milky Way, a dead star is spinning 220 times a second, and it's circling its companion in almost the most perfect orbit astronomers have ever measured. China's giant FAST radio telescope has just found it, and the shape of that orbit is a near flawless record of a billion year relationship between two stars.

New Study Assesses Titan's Resources and their Potential Uses

In a recent NASA-supported study, researchers assessed Titan's resource base and how it could be leveraged for ISRU. Compared with other locations under study (the Moon, Mars, etc.), they concluded that there is unrivaled potential for human exploration and settlement.



Venus’ Strange Rotation Was Likely Triggered By A High Velocity Moon-Sized Impactor

As it sped away from Venus in February 1974, NASA’s Mariner 10 spacecraft captured this seemingly peaceful view of Venus. But, contrary to its serene appearance, Venus is a world of intense heat, crushing atmospheric pressure and clouds of corrosive acid.  NASA/JPL-Caltech

Venus’ extraordinarily slow retrograde rotation was likely caused by a chance encounter with a moon-sized impactor. One that some 4.5 billion years ago likely slammed into our sister planet at a high angle and high velocity.

JWST Finds Exoplanets Choked by Diesel Smog

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres.

NASA Study Challenges Theories on Where the Ingredients for Life Came From

NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published in Science Advances, examines this history by looking at the ratio of phosphorus to nitrogen in iron meteorites and in younger objects known as chondrites.
