Peering into deep space, NASA’s James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself, bending and distorting the light of even more distant galaxies behind them. Each distorted arc, ring or multiplied galaxy image acts as a natural cosmic magnifying glass, offering astronomers a …

Observation The VLBI observation of JVAS B1938+666 used for this work was performed using a global VLBI array combining antennas from the Very Long Baseline Array (VLBA) and European VLBI Network (EVN) at 1.7 GHz for 14 h at a data recording rate of 512 Mbits s−1 (ID: GM068; Principal Investigator: McKean). The observing strategy followed a standard phase referencing mode only for the …

IN A NUTSHELL 🔭 Scientists detected a brief gravitational signal, suggesting the potential existence of a wormhole. 🌌 The signal, known as GW190521, challenges current understandings of space-time and relativity. 🌀 Researchers propose that the signal could be a gravitational echo from a collapsing wormhole. The discovery could revolutionize theories of general relativity and cosmology. In May 2019, a peculiar …

Kirill Kaprizov didn’t just reset the NHL marketplace by securing a record-shattering extension from the Minnesota Wild. He triggered an earthquake that is likely to produce reverberations across the industry. The Athletic spoke with seven certified player agents immediately after Kaprizov’s $136 million, eight-year extension ($17 million average annual value) with the Wild broke Tuesday morning to gauge what they …

In 2019, LIGO and Virgo recorded something truly bizarre – a gravitational wave event less than a tenth of a second in duration. Compared to the drawn-out chirps of black hole binaries on decaying orbital spirals, it was a sharp crack. The best explanation of the event, named GW190521, was a chance encounter of two black holes snaring each other …

For the first time, astrophysicists have measured the recoil — or “kick,” in the parlance — resulting from the birth of a new black hole that formed from the merger of two preexisting ones. The international team of researchers measured the ripples in the fabric of spacetime, known as gravitational waves, allowing them to get unprecedented insights into the turbulent …

It’s officially been 10 years since the first detection of gravitational waves. At the time, it had been 100 years since Albert Einstein predicted gravitational waves in his “Theory of General Relativity” paper. Hard to believe it has been 10 years since the first detection of gravitational waves. Back then, on Sept. 14, 2015, at 5:51 a.m., it had been …

Astronomers have for the first time measured the speed and direction of a newborn black hole, thanks to gravitational waves produced as it bounced away from the site of its parent black holes’ merger. This first complete measurement of black hole recoil comes almost exactly a decade after the first detection of gravitational waves — tiny ripples in spacetime first …

Smacking a planet-threatening asteroid comes with big responsibility. If we slam an impactor into an asteroid in exactly the wrong spot, the space rock may pass through a “gravitational keyhole” that actually brings it to Earth — which is exactly what planetary defense scientists and mission planners don’t want to happen. The keyhole is an area in space where the …
