Image: Hubble gazes at fluffy-looking galaxy

This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice’s Hair), NGC 4237 is classified as a flocculent spiral galaxy. This means that its spiral arms are not clearly distinguishable from each other, as in “grand design” spiral galaxies, but are instead patchy…

Image: Hubble investigates hungry galaxy

The subject of this image taken by the NASA/ESA Hubble Space Telescope, a spiral galaxy named NGC 1589, was once the scene of a violent bout of cosmic hunger pangs. As astronomers looked on, a poor, hapless star was seemingly torn apart and devoured by the ravenous supermassive black hole at the center of the galaxy.

What can you do with spiral graph? Help understand how galaxies evolve

Spiral structure is seen in a variety of natural objects, ranging from plants and animals to tropical cyclones and galaxies. Now researchers at the North Carolina Museum of Natural Sciences have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new and simple method is currently being applied in…

Are Permanent Magnets the Solution For Delivering Fusion Energy?

According to research published in the journal Physical Review Letters, permanent magnets akin to those used on refrigerators could speed the development of fusion energy. Phys.Org reports: In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the…

What is the gegenschein?

The sun’s counterglow – or gegenschein – is kind of a stargazers’ legend. What is it, and how can you see it? Erwin Matys and Karoline Mrazek of Project Nightflight explain. Source: https://earthsky.org/space/definition-what-is-the-gegenschein…

Image: Hubble spies galactic traffic jam

The barred spiral galaxy NGC 3887, seen here as viewed by the Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope, lies over 60 million light-years away from us in the southern constellation of Crater (the Cup). It was discovered on Dec. 31, 1785, by astronomer William Herschel. Source: https://phys.org/news/2020-03-image-hubble-spies-galactic-traffic.html…
