Asteroseismologists are combining data from TESS, Kepler, and eventually, JWST to study stellar oscillations in ‘infant’ stars, with the goal of creating new models for how such young stars form and evolve over time. Plus, JWST images Mars, Hubble images stars, and SpaceX manages to launch another Starlink mission in spite of weather delays.
As global temperatures rise, Earth observations show that glaciers are retreating and ice sheets are melting everywhere from Greenland to Antarctica while regions of the Arctic are getting greener. Plus, collaborations lead to new Mars and exoplanet discoveries, several rockets launched, and this week’s What’s Up involves Dr. Brian May of Queen.
Using layers of data from a variety of Martian missions, researchers have developed a machine learning algorithm that identified the actual crater from which a particular Martian meteorite originated. Plus, a radio heartbeat, and our last What’s Up and review of the season.
Using etched tungsten ditelluride at nearly absolute zero, scientists have observed electrons swirling around like whirlpools, behaving as a fluid. The methods could be used to design low-energy devices. Plus, eavesdropping on aliens, machine learning on solar data, and some new observatories are in the works.
A trio of stories examines the possibilities for finding life in strange, new places, including deep underground here on Earth, in the subsurface oceans of Europa, and fossilized within sedimentary rocks on Mars. Plus, a SpaceX launch, gamma-ray bursts, and this week’s What’s Up.
A basin region within Margaritifer Terra on Mars contains deposits of clay-bearing sediment that provide evidence of flowing water on the red planet as recently as 2.5 billion years ago. Plus, Mars mission updates, gravitational wave detection, rocket launches, and this week’s What’s Up.
