CHEOPS discovery defies planetary formation rules

We’re starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA’s CHEOPS mission places a rocky world right where it shouldn’t be. This “inside-out system” could challenge our current understanding of planetary formation.

Physicists break longstanding high-temperature superconductivity record at ambient pressure

Researchers from the Texas Center for Superconductivity (TcSUH) and the department of physics at the University of Houston have broken the temperature record for superconductivity at ambient pressure—a breakthrough that could eventually lead to more efficient ways to generate, transmit, and store energy.

TESS discovers a super-Earth exoplanet orbiting nearby star

Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and encircles its host in less than four days. The finding was reported in a paper published Feb. 28 on the arXiv pre-print server.

Could a recently detected ultra-high-energy neutrino be linked to new physics?

Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information about highly energetic cosmological events, such as exploding stars or supermassive black holes.

ATCA observations probe peculiar pulsar wind nebula Vela X

Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as Vela X. Results of the new observations, published March 2 on the arXiv pre-print server, provide more hints about the properties and nature of this nebula.

Next-gen interferometric diffusing wave spectroscopy achieves 20x signal boost in cerebral blood flow monitoring

Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on perfused tissue, the detected speckles, or “grains” of light fluctuate, or “dance,” at a rate proportional to blood flow in the volume sampled by the light. In brain tissue, this concept can be harnessed to measure the cerebral blood flow index (CBFi).

Dry ice detected in a planetary nebula for the first time

An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 on the arXiv pre-print server, resulted in the discovery of dry (carbon dioxide) ice in this nebula. This is the first time dry ice has been detected in a planetary nebula.

A 100-solar-mass black hole merger ripples spacetime, and may flash in gamma rays

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky.

Researchers realize room-temperature two-dimensional multiferroic metal

Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric (ME) coupling, allowing electric fields to influence magnetism.

This isn’t just another rocky world orbiting a red dwarf—this one’s special

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It’s a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding other M-dwarf exoplanets and their atmospheres. According to the authors of a new study, this new exoplanet could serve as “a reference system for highly irradiated rocky planets.”
