Binary black hole spin measurements from gravitational wave observations reveal the binary’s evolutionary history. More specifically, these measurements can be used to identify binaries caught in the so-called spin-orbit resonances. Einstein’s theory of general relativity first predicted the resonances. Later, the first ‘hints’ were found in gravitational wave data from LIGO and Virgo. In a…
While mapping radio waves in the universe, a team of astronomers spotted an unusual object releasing enormous energy. This object is unlike anything astronomers have seen before. According to astronomers, it could be a neutron star or a white dwarf with an ultra-powerful magnetic field. The team reported that the object releases a giant burst…
In the 1980s, Northwestern University‘s Farhad Yusef-Zadeh discovered highly organized, magnetic filaments in the Milky Way’s center. These filaments consist of cosmic-ray electrons orbiting the magnetic field at close to the speed of light. However, their origin remains unknown. A new image of the Milky Way’s center, taken by SARAO’s MeerKAT telescope, revealed almost 1,000…
Light at night in adults suppresses melatonin, a hormone primarily released by the pineal gland at night, and has long been associated with controlling the sleep-wake cycle. In children, bright light of a single intensity before bedtime has a robust melatonin suppressing effect. However, it remains elusive whether evening light of different intensities is related…
According to a new study, anxious young men and men who worry more are at greater risk of developing the cardiometabolic disease. Such men need to pay extra attention to maintaining a healthy weight and taking blood pressure or cholesterol medicines if required. The study- on men in the U.S.- suggests that more high-risk factors…
This year, an old tortoise named Jonathan has turned 190, becoming the oldest tortoise ever, earning a Guinness World record title. Estimated to be born in 1832, Jonathan has lived through two world wars, the Russian Revolution, seven monarchs on the British throne, and 39 US presidents. He officially earned the record title for the…
Plaque formation in your arteries is called atherosclerosis. The condition can potentially lead to serious heart problems. For years, it has been known that exercise and age affect the formation of plaques through a process known as atherosclerosis. However, it remains elusive how the geometrical features of the arteries affect plaque formation, although a dilated…
The world’s largest, most powerful, and most complex space science telescope ever- James Webb Space Telescope- has reached the second Sun-Earth Lagrange point or L2. The Webb safely arrived at L2 on January 24, 2022, at 2 p.m. EST. L2 is almost 1 million miles away from the Earth. It is an ideal location for…
Programming quantum computers require awareness of entanglement, the phenomenon in which measurement outcomes of qubits are correlated. Entanglement can determine the correctness of algorithms and the suitability of programming patterns. Entangled qubits give rise to Einstein’s characterization of “spooky action at a distance.” But that potency is equal parts a source of weakness. While programming,…
Astronomers discovered a black hole hidden in an enormous star cluster- B023-G078- in our closest neighboring galaxy Andromeda. Unlike any other black hole, this black hole- at one hundred thousand solar masses- is smaller but bigger than those born when stars explode. This makes the black hole the only confirmed intermediate-mass black hole. B023-G078 was…
