In September 2024, researchers predicted that the asteroid 2024 PT5 would soon join Earth as a short-lived “mini-moon.” Today, we’re giving a brief recap of how the prediction played out.
Though the North Star appears to be an unwavering single star, it’s actually a variable star belonging to a triple star system. This year, researchers reported a new mass estimate for the North Star and discovered spots on its surface.
As the solstice nears, we’re taking a look at four recent articles that share new findings from our home star.
What’s the origin of the dusty crescents in the disk around the young star MWC 758? Researchers have tracked the movements of two crescents to find out.
Astrobites reports on two research articles that find evidence for one of the most well-studied stars in the night sky having a binary companion.
An investigation of the Milky Way’s youngest super star cluster tests whether the winds of massive stars could be a source of cosmic rays.
Bombarded by powerful radiation or visited by comets carrying life’s ingredients, the Sun’s migration through the Milky Way likely contributed to the solar system’s ability to harbor life.
Is the high-energy radiation of a solar flare only rarely accompanied by a flash at visible wavelengths, or are visible-light flares more common than expected?
Astrobites reports on three neutron-star bow shocks photographed in unprecedented detail, revealing new insights into the hidden physics behind these cosmic collisions.
What has poked holes in the filamentary green structure in front of Cassiopeia A? A new research article offers answers.
Gravitational waves from collapsars, mass-gap black holes, and local supermassive black holes are the subject of this Monthly Roundup.
Astrobites reports on how machine learning can help researchers simulate the phase of planet formation in which planetary embryos interact, collide, and combine to form the planets we know and love.
