Last post by Toliman - Today at 10:02:05 PMHow Pluto got its 'heart'
https://news.arizona.edu/news/how-pluto-got-its-heart
Ever since the cameras of NASA's New Horizons mission discovered a large heart-shaped structure on the surface of the dwarf planet Pluto in 2015, this "heart" has puzzled scientists because of its unique shape, geological composition and elevation. Scientists from the University of Bern in Switzerland and the University of Arizona used numerical simulations to investigate the origins of Sputnik Planitia, the western teardrop-shaped part of Pluto's heart surface feature.
According to their research, Pluto's early history was marked by a cataclysmic event that formed Sputnik Planitia: a collision with a planetary body a little over 400 miles in diameter, roughly the size of Arizona from north to south. The team's findings, published in Nature Astronomy, also suggest that the inner structure of Pluto is different from what was previously assumed, indicating that there is no subsurface ocean.
"The formation of Sputnik Planitia provides a critical window into the earliest periods of Pluto's history," said Adeene Denton, a planetary scientist at the UArizona Lunar and Planetary Laboratory who co-authored the paper. "By expanding our investigation to include more unusual formation scenarios, we've learned some totally new possibilities for Pluto's evolution, which could apply to other Kuiper Belt objects as well."

Glowing Bipolar Bubble from Dying Star Expands into Space
In celebration of the 34th anniversary of the launch of NASA's legendary Hubble Space Telescope on April 24, 1990, astronomers took a snapshot of the Little Dumbbell Nebula. Also known as Messier 76, M76, or NGC 650/651, it is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring.
Before a red giant star burned out, it ejected a ring of gas and dust. The ring was probably sculpted by the effects of a binary companion star. This sloughed off material created a thick disk of dust and gas along the plane of the companion's orbit. The hypothetical companion star isn't seen in the Hubble image, and so it could have been later swallowed by the central star. The disk would be forensic evidence for that stellar cannibalism.
The photogenic nebula is a favorite target of amateur astronomers. Professional astronomers first took a spectrum in 1891, which indicated it was a nebula instead of a galaxy or a star cluster. They suggested that M76 might be similar to the donut-shaped Ring Nebula (M57), as seen instead from a side view.
