Excerpt: NASA’s Mars 2020 mission could visit two locations where microbial life may once have thrived. For NASA’s Mars 2020 rover, now being assembled at the agency’s Jet Propulsion Laboratory for launch in July 2020, the stakes could not be much higher. The $2.4 billion nuclear-powered rover is the most complex piece of machinery to ever make a ballistic beeline for the Red Planet. And after it lands in February 2021, its completion of one high-profile objective—collecting rock samples for eventual transport back to Earth—would ensure the rover sets the course for future Mars exploration for decades to come. But first, mission planners have to decide where on Mars this ambitious machine should actually go....

Stellar remains of famed 1987 supernova found at last

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.

Supernova of a Generation: Brightest Exploding Star in 40 Years Spotted

By -
Source:   IB Times Excerpt: Astronomers from Berkeley have discovered the closest supernova, or exploded star, in 40 years in the Pinwheel Galaxy, located just 21 million light-years from Earth. ...Being the source of most of the chemical elements in the universe heavier than iron, supernovas also play an important role in the evolution of galaxies and planetary systems. They also seed the rest of space with elements such as carbon, oxygen and nitrogen, and can "nudge" gas clouds into collapsing to form new star systems. www.ibtimes.com/art/services/print.php
