212408: More black hole weirdness: They bend light so much they self-illuminate

Direct link More black hole weirdness: They bend light so much they self-illuminate

9 Jul 2020, 13:00 UTC I like to think that anyone is capable of some self-reflection. I would not, however, have thought to include black holes in that ability.

8 Jul 2020, 17:19 UTC Neutrinos are puzzling things. They’re tiny particles, almost massless, with no electrical charge. They’re notoriously difficult to detect, too, and scientists have gone to great lengths to detect them. The IceCube Neutrino Observatory, for instance, tries to detect neutrinos with strings of detectors buried down to a depth of 2450 meters (8000 ft.) in the dark Antarctic ice.

7 Jul 2020, 16:38 UTC For space scientists of all stripes, few goals are as crucial as bringing pieces of Mars, of asteroids, of other planets and moons back to Earth for the kind of intensive study only possible here. Space missions can, and have, told us many truths about the solar system, but having a piece of Mars or Europa or an asteroid to study in a lab on Earth is considered the gold standard for learning about the actual composition of other bodies, their histories and whether they could — or once did — harbor life.

7 Jul 2020, 13:00 UTC There is something paradoxical about the Moon. Or perhaps, more accurately, our perception of it.

Direct link Why Wait For Betelgeuse To Blow Up? See Two Bright Supernovae Tonight

6 Jul 2020, 18:27 UTC Why wait around for Betelgeuse to blow up to see a supernova in your lifetime? If you have a 6-inch telescope and dark sky you can see one right now. Two actually. Both are visible in the western sky at nightfall in the neighboring constellations Virgo and Coma Berenices.

Direct link Ice Hunt on the Moon Reveals Hidden Heavy Metal

2 Jul 2020, 18:23 UTC Our beautiful Moon, serenely circling our world as it illuminates our evenings and tugs at our tides, is thought to have been born from a violent and catastrophic collision between a freshly-formed Earth and a Mars-sized wayward protoplanet almost four and a half billion years ago. This “giant impact hypothesis” is generally accepted because it provides causation for many aspects of why the Moon is how we see it today. But there have always been some discrepancies with the theory—one of which being the difference in distribution and amount of some heavy metals in the Moon’s composition based on when the impact event occurred during Earth’s formative years.
