Images from the WISPR instrument — short for Wide-field Imager for Solar Probe — on board NASA’s Parker Solar Probe spacecraft have provided the first complete view of the ring of dust along Venus’ orbit. The dust ring stretches diagonally from the lower left to the upper right of the image, marked by the red…
A recent view captured by NASA/ESA Hubble Space Telescope impressively demonstrates the concept of gravitational lensing. Hubble captured an extraordinary view of galaxy cluster Abell 2813, located in the constellation of Cetus. Also known as ACO 2813, the cluster is so distant that light from it takes approximately 3.4 billion years to travel to reach…
In this frame from the new visualization, a supermassive black hole weighing 200 million solar masses lies in the foreground. Its gravity distorts light from the accretion disk of a smaller companion black hole almost directly behind it, creating this surreal view. Different colors for the accretion disks make it easier to track the contributions…
Researchers work on one of the quantum network nodes, where mirrors and filters guide the laser beams to the diamond chip. Scientists worldwide are working on quantum internet to let quantum devices exchange some information within an environment that harnesses quantum mechanics’ weird laws. It will use quantum bits or qubits that can be 0…
Credit: Public Domain The boiling point of water is 100 degrees Celcius. Water canes its density during phase transition. Turnin up-the pressure could increase the boiling point until a pressure of 221 atmospheres where it boils at 374 degrees Celcius. In a new study, something strange happened: the liquid and gas merge into a single…
Museums hide several treasures locked in the vaults. It offers scientists some of the original pieces of art from the ancient era. Recently, a group of researchers from EPFL‘s Audiovisual Communications Laboratory in the School of Computer and Communication Sciences (IC) accessed some of the original photographic plates and images of the scientist and inventor…
Systemic lupus erythematosus (SLE) is an autoimmune disease in which the body mistakenly attacks healthy tissue. The condition makes the body’s immune system malfunction and begins assaulting various organs, particularly the skin and kidneys. The underlying reasons for lupus are obscure, yet contaminations are thought to play a role. A previous study suggested that immune…
Ultralight bosons are theoretical particles that have a mass of less than a billionth of the mass of an electron. As they rarely interact with their surroundings, they thus have far eluded searches to confirm their existence. If they are present, then the ultralight boson, such as axions, will form dark matter. In 2019, it…
Where available, honeybee hive products, including honey, beeswax, and brood. They have been of considerable importance to ancient communities, both as a nutritional source and for medicinal, cosmetic, and technological purposes. Honey is essential insect-related food globally. It is a rare sweetener source, comprises 80–95% sugar (carbohydrate), several important vitamins and minerals, and components that…
Atom interferometry is the technique that underlies most of our precision measurements using atom interferometers. Using this technique, it is possible to measure the gravitational field of the Earth or detect gravitational waves. For the first time, scientists from Germany managed to successfully perform atom interferometry in space- onboard a sounding rocket. They have established…
