Formation Theory Explains Unusual Characteristics of Interstellar Object 'Oumuamua

Since its discovery in 2017, an air of mystery has surrounded the first known interstellar object to visit our solar system, an elongated, cigar-shaped body named 'Oumuamua (Hawaiian for "a messenger from afar arriving first").

NASA Missions Capture the Power of Shock Waves in Nova Explosion

Unprecedented observations of a nova outburst in 2018 by a trio of satellites, including two NASA missions, have captured the first direct evidence that most of the explosion's visible light arose from shock waves -- abrupt changes of pressure and temperature formed in the explosion debris.

Using Webb to Explore the Dark Birthplaces of High-Mass Stars

High-mass stars, which are eight or more times the mass of our Sun, live hard and die young. They often end their short lives in violent explosions called supernovas, but their births are much more of a mystery.

Astronomers Make the First Measurement of Wind Speed on a Brown Dwarf

Astronomers have used the National Science Foundation's Karl G. Jansky Very Large Array and NASA's Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf -- an object intermediate in mass between a planet and a star.

The Tokyo Skytree Used to Verify Einstein's Theory of General Relativity

In another verification of the validity of Einstein's theory of general relativity, published in Nature Photonics, scientists from the RIKEN Center for Advanced Photonics and Cluster for Pioneering Research, with colleagues, have used two finely tuned optical lattice clocks, one at the base and one on the 450-meter observatory floor of Tokyo Skytree, to make new ultraprecise measurements of the time dilation effect predicted by Einstein's theory of general relativity.

Novel Methods of Searching for Dark Matter

Dark matter, which cannot be physically observed with ordinary instruments, is thought to account for well over half the matter in the Universe, but its properties are still mysterious. One commonly held theory states that it exists as 'clumps' of extremely light particles.
