To test the approach, they compared more than 1,500 one-dimensional Spheral simulations with asteroid deflection results. (Representational image)MARK GARLICK/SCIENCE PHOTO LIBRARYResearchers in the United States are developing three-dimensional simulations to examine how a nuclear device could be used to deflect or potentially disrupt an asteroid threatening Earth. The team from Lawrence Livermore National Laboratory (LLNL) uses Spheral simulation code to more accurately model how an asteroid might respond when X-rays from a nuclear device detonated near its surface rapidly heat and vaporize material. After validating the approach against established asteroid-deflection models, researchers used Spheral to study three complex disruption scenarios.

NASA’s Roman Space Telescope prepares to unleash a flood of new cosmic discoveries - The Brighter Side of News
Roman is designed to return about 1.4 terabytes of data daily, with observations becoming publicly available after processing. A collaboration of roughly 900 astronomers is preparing to search those observations for planets, black holes and cosmic explosions. The telescope’s surveys could sharpen measurements of dark energy, but their major discoveries still lie ahead. A distant star briefly brightens. A supernova appears in a galaxy. Somewhere else, an unseen object bends passing starlight. NASA’s Nancy Grace Roman Space Telescope is designed to capture such changes across crowded stretches of sky, then make its observations available for others to investigate. The challenge will be keeping up. Roman is expected to return about 1.4 terabytes of data daily during operations. Jessica Lu, an astronomy associate professor at the University of California, Berkeley, and David Weinberg of Ohio State University have organized a collaboration of roughly 900 astronomers to prepare. Their effort connects two ambitions: finding unusual objects in the Milky Way and understanding why the universe’s expansion is accelerating.
Scientists discover a way to reverse coral bleaching at record speed - Phys.org
For the first time, scientists have observed bleached corals on the brink of death fully recover through brief contact with healthy clones. Ghostly white corals returned to full health in a laboratory setting within seven weeks, the fastest documented recovery to date, according to a study published in Science Advances.

Scientists Find a ‘Ghostly Green’ Star, and That’s Not the Only Crazy Color - CNET
High school science class taught us that stars come in very specific colors. You have cooler stars that are red, orange and yellow. Then you have hotter, larger stars that are white and blue. It turns out that much like the wind in the movie Pocahontas, stars also come in all sorts of colors, including green and pink. The discovery was outlined in a study published this month in RAS Techniques and Instruments. According to the lead author, Mark Hollands of Warwick University’s astronomy and astrophysics group, the humble white dwarf star is the centerpiece of this chromatic curiosity.
