Study determines stellar mass and origin of a protostellar system

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted molecular line observations of a protostellar system known as VLA 1623. Results of the observational campaign, published June 18 on the pre-print server arXiv, yield new information regarding stellar mass and origin of this system.

Re-analyzing LHC Run 2 data with cutting-edge analysis techniques allowed physicists to address old discrepancy

Supersymmetry (SUSY) is an exciting and beautiful theory that answers some of the open questions in particle physics. It predicts that all known particles have a “superpartner” with somewhat different properties. For example, the heaviest quark of the Standard Model, the top quark, would have a superpartner called the top squark, or simply the “stop.” […]

NASA’s Juno probe gets a close-up look at lava lakes on Jupiter’s moon Io

New findings from NASA’s Juno probe provide a fuller picture of how widespread the lava lakes are on Jupiter’s moon Io and include first-time insights into the volcanic processes at work there. These results come courtesy of Juno’s Jovian Infrared Auroral Mapper (JIRAM) instrument, contributed by the Italian Space Agency, which “sees” in infrared light. […]

Looking for atmospheres in the ultimate quest for extraterrestrial life

To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba has used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations. Zieba graduated cum laude from Leiden University […]

Surprising phosphate finding in NASA’s OSIRIS-REx asteroid sample

Scientists have eagerly awaited the opportunity to dig into the 4.3-ounce (121.6-gram) pristine asteroid Bennu sample collected by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security—Regolith Explorer) mission since it was delivered to Earth last fall. They have hoped the material would hold secrets of the solar system’s past and the prebiotic chemistry that […]

Why NASA astronauts are delayed at the space station after Boeing Starliner launch

When two veteran NASA astronauts blasted off on a test drive of Boeing’s new capsule, they expected to head home from the International Space Station in a week or so.

Time-compression in electron microscopy: Terahertz light controls and characterizes electrons in space and time

Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for the all-optical control, compression, and characterization of electron pulses within a transmission electron microscope using terahertz light. Additionally, the researchers have discovered substantial anti-correlations in the time […]

Determining refractive index at relativistic speeds

If you studied advanced physics at high school, there’s a good chance that you remember Snell’s law, which states how a ray of light bends when it crosses a boundary between two media. According to this law, the ratio of the sines of the incident and refracted angles is a non-universal constant, later understood as […]
