A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-84.
A luminous black hole already classified as an active galactic nucleus brightened suddenly in recent ground and space observations, and the cause may be due to a sudden flip in the magnetic poles. Plus, community science, rockets, Ingenuity, and an interview with Dr. Cathy Weitz from Planetary Science Institute.
Data from the Hubble Space Telescope has determined that the newly discovered companion of a star that went supernova had its outer hydrogen layer siphoned off before the explosion. The results support the theory that massive stars generally form and evolve as binary systems. Plus, rocks from space, Crew-4 comes home, searching for life beyond Earth, and another Canon lens review.
The flash of a pulsar about 3,000 light-years from our solar system was caused by a ‘black widow’ binary consuming a smaller star. Intriguingly, a third companion star is orbiting the pair, which may have originated near the Milky Way’s center. Plus, the Sun is ramping up, Chandra releases more sonification videos, and this week’s What’s Up is all about occultations.
Using spherical grains called ooids, found on Earth in shallow, tropical waters, scientists have found a possible mechanism for the formation of hydrocarbon sand on Titan. Plus, rocket launches, Jupiter and Mars, space explosions, and this week in rocket history, we look back at Britain’s Ariel satellite program.
Using data from TESS, a new paper presents evidence for the discovery of thirty potential comets orbiting in the Beta Pictoris system. Plus, astrobiology research, water on the Moon, solar system formation, and a review of “The Adam Project” starring Ryan Reynolds.
