Study hints at the existence of the closest black holes to Earth in the Hyades star cluster      (via sciencedaily.com) 

A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever detected.

Ravenous black hole consumes three Earths'-worth of star every time it passes      (via sciencedaily.com) 

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

Webb reveals new structures within iconic supernova      (via sciencedaily.com) 

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.

Scientists detect and validate the longest-period exoplanet found with TESS      (via sciencedaily.com) 

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Tiny, shape-shifting robot can squish itself into tight spaces      (via sciencedaily.com) 

Imagine a robot that can wedge itself through the cracks in rubble to search for survivors trapped in the wreckage of a collapsed building. Engineers are working toward to that goal with CLARI, short for Compliant Legged Articulated Robotic Insect.

Telescopes help unravel pulsar puzzle      (via sciencedaily.com) 

With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.

Paving the way for advanced quantum sensors      (via sciencedaily.com) 

Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several new studies show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Researchers were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.

Mysterious Neptune dark spot detected from Earth for the first time      (via sciencedaily.com) 

Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a dark spot on the planet has ever been observed with a telescope on Earth. These occasional features in the blue background of Neptune's atmosphere are a mystery to astronomers, and the new results provide further clues as to their nature and origin.

Do measurements produce the reality they show us?      (via sciencedaily.com) 

The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

How a cup of water can unlock the secrets of our Universe      (via sciencedaily.com)     Original source 

A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.

New type of star gives clues to mysterious origin of magnetars      (via sciencedaily.com)     Original source 

Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they form. Now, using multiple telescopes around the world, researchers have uncovered a living star that is likely to become a magnetar. This finding marks the discovery of a new type of astronomical object -- massive magnetic helium stars -- and sheds light on the origin of magnetars.
