Many Worlds 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.
Bad Astronomy 7 Jul 2020, 13:00 UTC There is something paradoxical about the Moon. Or perhaps, more accurately, our perception of it.
Astro Bob 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.
Skymania News 6 Jul 2020, 15:04 UTC Noctilucent clouds are a beautiful sight. They lie on the edge of space and have an astronomical origin.
Lights in the Dark 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.
First Exposed Planetary Core Discovered – An Extremely Unusual Planet in the So-Called “Neptune Desert”2 Jul 2020, 08:38 UTC The newly discovered Neptune-sized exoplanet TOI 849 b orbits its star in just 18 hours and offers a unique opportunity to peer inside a planet to investigate how planets form. Was it like Jupiter before its atmosphere was stripped or did it fail to form one in the first place?
Universe Today 1 Jul 2020, 04:08 UTC When NASA’s new Perseverance Martian rover launches in a little over a month it will have a small robotic stow-away on board. Ingenuity is a small helicopter, with a fuselage about the size of a softball and two extending rotors that measure about 4 feet across. It was attached to the bottom of the rover’s chassis in April, and NASA recently released details about it’s technically challenging release process.
