Measuring the vast quantities of cosmic dust in interstellar space may be a key to unlocking various mysteries of the cosmos, including how the grains form and whether new types of galaxy are obscured by the particle clouds. Powered by WPeMaticoRead More →
Russian astronomers have conducted a study of large-scale morphology and kinematics of the ionized gas in the galaxy Markarian 6. The research, in addition to mapping the ionized gas in the stellar disc, has identified a system of faint, extended emission filaments in the galaxy. The finding is detailed in a paper published September 16 on the arXiv pre-print server. Powered by WPeMaticoRead More →
Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after they orbit another star and explode as Type Ia supernovae. Powered by WPeMaticoRead More →
All living beings need cells and energy to replicate. Without these fundamental building blocks, living organisms on Earth would not be able to reproduce and would simply not exist. Powered by WPeMaticoRead More →

A team of astronomers led by Coryn Bailer-Jones of the Max Planck Institute for Astronomy has tracked the interstellar object ‘Oumuamua to several possible home stars. The object was discovered in late 2017 – this was the first time astronomers have been able to observe an astronomical object from another star system visiting our own Solar System. Bailer-Jones and his colleagues used data from the ESA astrometry satellite Gaia to find four plausible stars where ‘Oumuamua could have begun its long journey, more than a million years ago.

The Milky Way is Still Rippling from a Galactic Collision Millions of Years Ago Between 300 million and 900 million years ago, our Milky Way galaxy nearly collided with the Sagittarius dwarf galaxy. Data from the ESA’s Gaia mission shows the ongoing effect of this event, with stars moving like ripples on the surface of a pond. The galactic collision is part of an ongoing cannibalization of the dwarf … Continue reading “The Milky Way is Still Rippling from a Galactic Collision Millions of Years Ago” The post The Milky Way is Still Rippling from a Galactic Collision Millions of Years Ago appeared first onRead More →
