Old Star Pushes Out Charged Particle Jet Held Together by a Magnetic Field

An old star, IRAS 15445-5449, has begun to push out a jet of charged particles that glow with radio waves.

Experimental Evidence Supports Breakdown of Larger Structures Theory for Formation of Buckyballs

Researchers at the Virginia Tech Carilion Research Institute have reported the first experimental evidence that supports the theory that a soccer ball-shaped nanoparticle commonly called a buckyball is the result of a breakdown of larger structures rather than being built atom-by-atom from the ground up.

Balloon-Borne X-ray Telescope to Study How Black Holes Devour Matter

In a few days, a balloon-borne telescope sensitive to the polarization of high-energy “hard” X-rays will ascend to the edge of the atmosphere above Fort Sumner, N.M., to stare fixedly at black holes and other exotic astronomical objects.

New Method for Determining Amount of Quantum Entanglement

Two researchers at UCL Computer Science and the University of Gdansk present a new method for determining the amount of entanglement – a quantum phenomenon connecting two remote partners, and crucial for quantum technology - within part of a one-dimensional quantum system.

Compact Galaxies with ‘Red Nuggets’ Didn’t Disappear

In 2005 the Hubble Space Telescope spotted unusually small galaxies densely packed with red stars in the distant, young universe. They were nicknamed "red nuggets," not only because they are small and red but also their existence challenged current theories of galaxy formation, making them precious in astronomers' eyes.

Voyager 1 Ventures into Interstellar Space

NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

New Model to Study Pulsational Dynamics of Molecular Cloud Fluctuations at Star Formation Sites

The birth of stars is an event that eludes intuitive understanding. It is the collapse of dense molecular clouds under their own weight that offers the best sites of star formation. Now, Pralay Kumar Karmakar from the Department of Physics at Tezpur University, Assam province, India, and his colleague have proposed a new model for investigating molecular cloud fluctuations at sites of star formation and thus are able to study their pulsational dynamics, in a paper published in EPJ D.

Largest Known Population of Globular Clusters Uncovered by Hubble

NASA's Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core of the giant grouping of galaxies known as Abell 1689.

ESO Telescopes Deliver Clearer View of Central Galactic Bulge

Two groups of astronomers have used data from ESO telescopes to make the best three-dimensional map yet of the central parts of the Milky Way. They have found that the inner regions take on a peanut-like, or X-shaped, appearance from some angles. This odd shape was mapped by using public data from ESO’s VISTA survey telescope along with measurements of the motions of hundreds of very faint stars in the central bulge.

Astronomers Begin Mapping Location of Giant Gas Clouds in the Galaxy

A UNSW-led team of astronomers has begun to map the location of the most massive and mysterious objects in our galaxy – the giant gas clouds where new stars are born.
