Hubble Peers Through The Mysterious Shells of This Gigantic Elliptical Galaxy

Hubble Peers Through The Mysterious Shells of This Gigantic Elliptical Galaxy

Take a good look at the latest image provided by the Hubble Space Telescope. It shows a huge elliptical galaxy called NGC 474 which lies about 100 million light-years away from us. At about two and a half times larger than our Milky Way, it really is a monster. Notice its odd structure – mostly … Read more

‘Traffic calming’ boosts breeding on coral reefs — ScienceDaily

A new drug to treat liver disease? Rutgers researchers discover hormone has therapeutic effects on non-alcoholic fatty liver disease in mouse study -- ScienceDaily

Coral reef fish breed more successfully if noise from motorboats is reduced, new research shows. Scientists have introduced ‘traffic calming’ on three reefs for an entire breeding season, reducing the number of boats within 100m and reducing the speed of those within that distance. They then tracked the breeding of fish called spiny chromis – … Read more

A new drug to treat liver disease? Rutgers researchers discover hormone has therapeutic effects on non-alcoholic fatty liver disease in mouse study -- ScienceDaily

Achieving structurally uniform nanocarbons – ideally as single molecules – is a great challenge in the field of nanocarbon science in order to correctly relate structure and function. Thus, the construction of structurally uniform nanocarbons is crucial for the development of functional materials in nanotechnology, electronics, optics and biomedical applications. An important tool for achieving … Read more

Ghostly Unseen “Mirror World” Might Be Cause of Cosmic Controversy With Hubble Constant

Astrophysics Space Dark Matter Concept

According to new research, an invisible ‘mirror world’ of particles that only interacts with our world through gravity could be the key to solving the Hubble constant problem. According to new research, an invisible ‘mirror world’ of particles that only interacts with our world through gravity could hold the key to solving a major puzzle … Read more

A dazzling Hubble collection of supernova host galaxies

A dazzling Hubble collection of supernova host galaxies

Covering from 2003 to 2021, this collection of NASA/ESA Hubble Space Telescope images features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurement of the Hubble constant, the rate of … Read more

Here's what's come out of US congress hearings on 'unidentified aerial phenomena'

Credit: CC0 Public Domain The United States Congress recently held a hearing into US government information pertaining to “unidentified aerial phenomena” (UAPs). The last investigation of this kind happened more than 50 years ago, as part of a US Air Force investigation called Project Blue Book, which examined reported sightings of unidentified flying objects (note … Read more

Unexpected flow behavior in liquid metals

Invisible helium atoms provide exquisitely sensitive test of fundamental theory

Some metals are in liquid form, the main example being mercury. But there are also huge amounts of liquid metal in the Earth’s core, where temperatures are so high that some of the iron is molten and undergoing complex flows. A team from Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now simulated a similar process in the laboratory … Read more
