SpaceX’s test flight of Starship SN15 went off without a hitch today, May 5, 2021. Following 4 Starship prototypes that exploded upon landing after their high-altitude flight tests, the SN15 landed safely.
The gravity of the Large Magellanic Cloud – one of the Milky Way’s satellite dwarf galaxies – is collecting stars behind it in a trail, like the wake from a boat, as it travels through our galaxy’s halo.
Every year millions of tons of dust from the Sahara Desert are swirled up into the atmosphere and carried across the Atlantic. Research suggests that, as the climate changes, Saharan dust transport will decrease.
Astronomers have managed to detect very long wavelength radio emission from a well-studied, repeating fast radio burst, called FRB 20180916B. What’s more, the longer wavelengths arrive 3 days after the shorter wavelength counterpart of the signal! Why?
During its final flyby this month, the spacecraft OSIRIS-REx took an image of the location where it collected a sample from asteroid Bennu’s surface. It’ll return to Earth 2 years from now, providing scientists with clues to the creation of our solar system.
Comet 2I/Borisov is the 2nd known object to pass near our sun from outside our solar system. Its 2019 pass near our sun might have been its first-ever interaction with a star. If so, it’s among the most pristine, or unspoiled, objects yet known.
Apophis’ flyby in early March 2021 enabled astronomers to conclude there’s no chance this asteroid will strike Earth anytime soon. “A 2068 impact is not in the realm of possibility anymore,” one scientist said, “and our calculations don’t show any impact risk for at least the next 100 years.”
A new theory about ‘Oumuamua suggests the weird object that passed through our solar system in 2017 was a remnant of a Pluto-like world from another solar system. As one scientist said, “‘Oumuamua may be the first piece of an exoplanet brought to us.”
