https://www.science.org/content/article/stellar-remains-famed-1987-supernova-found-last By DANIEL CLERY , Science.  Excerpt: When a nearby star exploded in 1987, it created the first supernova visible to the naked eye in 4 centuries and became one of the most intensely studied objects in space. Now, after more than 35 years of searching, researchers have finally discovered the cinder left behind. Using NASA’s new giant space telescope JWST, astronomers spotted  glowing gas at the center of the blast that can only have been energized by something hot and compact inside it , they report this week in Science. They believe a neutron star, all that remains of the shattered star, is responsible....

Planets around dead stars offer glimpse of the Solar System’s future—after the Sun swallows us up

https://www.science.org/content/article/planets-around-dead-stars-offer-glimpse-solar-system-s-future-after-sun-swallows-us By JONATHAN O’CALLAGHAN , Science.  Excerpt: In about 5 billion years the Sun will balloon up into a red giant, consuming Mercury, probably Venus, and maybe even Earth. But even if the outer planets avoid being swallowed up, they might eventually get pulled in or ejected from the Solar System. A new discovery suggests they can survive intact. Using NASA’s JWST space telescope, astronomers have for the first time directly imaged planets on Solar System–like orbits around white dwarfs, the dead stars left after Sun-like stars swell into red giants and subside. The planets follow orbits resembling those of the giant planets in the outer Solar System—big enough for them to have escaped the inferno.... For GSS A Changing Cosmos chapter 1.

JAPAN'S "SNIPER" MISSION PINPOINTS LANDING ON THE MOON

https://skyandtelescope.org/astronomy-news/japans-sniper-mission-pinpoints-landing-on-the-moon/ By DAVID DICKINSON , Sky & Telescope.  Excerpt: Today, the Japanese Aerospace Exploration Agency (JAXA  Smart Lander for Investigating the Moon (SLIM)  spacecraft pitched over in its lunar orbit, and began its long descent to the Moon's surface. Touchdown occurred at 10:20 a.m. EST / 15:20 UT; NASA’s  Deep Space Network  in Madrid picked up the lander's signal shortly afterward, but problems have ensued. ...SLIM was designed to test the innovative “smart eyes” landing technology, which involves image-matching to aid navigation. The mission was also designed to demonstrate a pinpoint landing, that is, within 100 meters of the target, on a 6- to 8-degree slope. SLIM has a Multi-Band Camera camera on board and, if it is able to, it will deploy two baseball-size rovers on the lunar surface named Lunar Exploration Vehicle 1 and 2. These will hop and roll along the lunar surface, imagi
