Since 1967, researchers have identified many pulsars. Some of these are among the most reliable clocks in the cosmos, thanks to their incredibly regular rotations. The fastest can spin around hundreds or thousands of times each second. Even for an object that small, that’s an incredible rate ...
NGC 247 is a beautiful spiral galaxy that we see almost edge-on. It’s smaller than the Milky Way, but it contains some bright nurseries—dense gaseous regions where new stars form. Its most unusual feature, though, is a dark “void” on one side of the galaxy’s core, which looks l...
Quasars, powered by gas accretion onto supermassive black holes1,2, rank among the most energetic objects in the Universe3,4. Although they are thought to be ignited by galaxy mergers5,6,7,8,9,10,11 and affect the surrounding gas12,13,14,15, observational constraints on both processes re...
—What's the most massive object in the universe? Even the largest-known black hole in the universe— a cosmic titan named TON 618, weighing an estimated 40 billion solar masses — appears to be near the theoretical limit of how big black holes can get. This limit comes from the fact ...
With some experts predicting the most violent outbreak of solar activity in modern history. => 一些专家预测现代史上最激烈的太阳活动爆发。 itÂs never been more important to understand the secrets of the Sun. => 理解太阳的秘密从未如此重要。
Once it’s in that spinning disc, the matter (usually hydrogen gas as this is the most common element in the Universe) will settle into a nice, happy orbit around the black hole, far away from the point of no return: the event horizon. The event horizon is the sphere around the ...
The phenomenon of the Dark Matter is one of the most intriguing mysteries in the Universe. In fact, not only it implies the existence of unknown Science and in particular of unknown Physics, but it concerns the fabrics itself of the Universe. A new Law of Nature, yet to be discovered, ...
Nicknamed Tabby's star, the object would dip in brightness at irregular intervals and for odd lengths of time, sometimes by as much as 22 percent. Different theories were invoked, including the possibility of an alien megastructure, but nowadays, most researchers believe the star to be ...
What can ripples in spacetime reveal about black holes? Quite a bit, it turns out The most powerful explosions in the universe could reveal where gold comes from AI designs 50 gravitational wave detectors that could outperform human-made ones Where did this extremely magnetic, dense and dead...
The data processing is also described in ref. 9, and we refer to that paper for a detailed discussion. Here we only mention that we used the pipeline developed by the ESA NIRSpec Science Operations Team and the NIRSpec GTO Team. Most of the processing steps in the pipeline adopt the ...
