New ultra-short-period exoplanet discovered

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected a new ultra-short-period exoplanet. The newly found alien world is nearly two times larger than the Earth and orbits its host star in less ...

Cosmic dawn observational progress with NenuFAR

The NenuFAR Cosmic Dawn project has taken an important step in the exploration of the Cosmic Dawn, this key period in our universe marked by the formation of the first stars. An upper limit on the amplitude of the neutral ...

Breaking the 10-petawatt limit with a new laser amplification

Ultra-intense ultrashort lasers have a wide-ranging scope of applications, encompassing basic physics, national security, industrial service, and health care. In basic physics, such lasers have become a powerful tool for ...

Using smart materials to deploy a Dark Age explorer

One of the most significant constraints on the size of objects placed into orbit is the size of the fairing used to put them there. Large telescopes must be stuffed into a relatively small fairing housing and deployed to ...

Entropy could be key to a planet's habitability

We all know that to have life on a world, you need three critical items: water, warmth, and food. Now add to that a factor called "entropy." It plays a role in determining if a given planet can sustain and grow complex life.

Dwarf planet Eris is 'squishier' than expected

University of California, Santa Cruz Professor of Planetary Sciences Francis Nimmo recently co-authored a Science Advances paper about the internal structure of the dwarf planet Eris.

An exo-Neptune beat the odds and kept its atmosphere

As planet-hunting scientists find more and more planets, they've encountered some puzzles. One of them concerns the lack of Neptune-size worlds orbiting close to their stars. Astronomers think that these planets aren't massive ...

Detection of environmental PFAS by interrupted energy transfer

PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) ...
