About 900 million miles away in two different galaxies, a black hole and a neutron star merged, and their gravitational waves have been detected here on Earth. These detections add another type of merger to the collection so far discovered. Plus, new composition data on Mars’ south polar cap and a look back at the Tunguska Event. #AsteroidDay
After a successful touchdown on Mars last week, the Zhurong lander has sent back both black and white and color images. Plus, pulsars, ocean depths, heavy metal vapor, radioactive elements, and this week’s What’s Up which includes a total lunar eclipse!
Two new studies used data from Cassini’s Grand Finale observations of Saturn and found that the magnetic fields and a wave in the rings provide insight into the core structure and composition of the gas giant. Plus, cosmic rays, how Mayans shaped the Earth, and a review of books by Charles C. Mann.
A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.
Data analyzed from the NICER telescope aboard the ISS contains evidence of X-ray boosts accompanying radio burst detections, releasing more energy than expected as “giant radio pulses”. Plus, machine learning, intraterrestrial life, all the volcanoes, and updates on SN15 and Ingenuity.
Scientists have been looking for the reclusive neutron star expected to be at the center of supernova 1987A for over thirty years, and they may have finally found it in new images from the Chandra and NuSTAR observatories. Plus, a look at conflicting papers on the object that wiped out the dinosaurs, a roundup of news, and this week’s What’s Up.
