Astronomers have spotted something strange and spectacular: a mysterious object that keeps emitting pulses every 44 minutes. In a press release from Australia's Curtin University, which was part of the international team that detected the object just 15,000 light-years away in our Milky Way galaxy, astronomers explained that the find was all the more stunning because the signal is coming in the form of both X-rays and radio waves. The object, which was named ASKAP J1832-0911 after Australia's

What just happened? An international team of researchers have discovered a cosmic anomaly unlike anything previously witnessed. The object in question, located roughly 15,000 light-years away in our very own Milky Way galaxy, has been observed emitting both radio waves and X-ray radiation. The celestial body, dubbed ASKAP J1832- 0911, was initially found by astronomers using the Australian Square Kilometer Array Pathfinder (ASKAP), a radio telescope located in Australia.

A small team led by Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study’s School of Natural Sciences, has discovered an extraordinary trans-Neptunian object (TNO), named 2017 OF 201 , at the edge of our solar system. The TNO is potentially large enough to qualify as a dwarf planet, the same category as the much more well-known Pluto.

When I first learned about Diffie-Hellman and especially elliptic curve Diffie-Hellman, I had one rather obvious question: Why elliptic curves? Why use this strange group that seems rather arbitrary, with its third intersection of a line and then reflected? Why not use, say, the Monster Group? Surely a monster is better equipped to guard your secrets than some curve thing named after, but legally distinct from, a completely different curve thing!

Scientists are intrigued after spotting a highly unusual celestial object lurking at the very edge of our solar system. It's possible the trans-Neptunian object, dubbed 2017 OF201, is large enough to qualify as a dwarf planet, making it an "extreme 'cousin' of Pluto," according to Princeton postdoc Sihao Cheng, who coauthored a yet-to-be-peer-reviewed paper on the findings.

What the research is: Kangaroo is a new flash cache that enables more efficient caching of tiny objects (objects that are ~100 bytes or less) and overcomes the challenges presented by existing flash cache designs. Since Kangaroo is implemented within CacheLib, Facebook’s open source caching engine, developers can use Kangaroo through CacheLib’s API to build their own customized cache services. We partnered with Carnegie Mellon University (CMU) on this research. The resulting paper won the Best

Motivation Compact object headers were introduced as an alternative object-header layout by JEP 450 in JDK 24. Features of this size are best introduced carefully and gradually, so we introduced it as an experimental feature. Since JDK 24, compact object headers have proven their stability and performance. T

The universe is a chaotic place filled with exploding stars, material falling into black holes, and rogue planets wandering off on their own. All that chaos makes astronomers suspicious when they glimpse a hint of perfection in the cosmos, like a bubble of material left over from the death of a star that appears to be in perfectly symmetrical shape. Astronomers recently discovered the remnant of a galactic supernova with a remarkable circular symmetry, making it stand out as one of the most per

Planet Nine is a hypothesized massive planet, first proposed in 2014, that is speculated to orbit far out in the solar system. It has not been detected formally. Instead, astronomers have inferred its presence from perceived perturbations of the orbits of some Trans-Neptunian Objects (TNOs). The planet is estimated to be 2 to 4 times the radius, and about ten times the mass of the Earth. The best candidate yet for the elusive Planet Nine has been spotted in two deep infrared surveys taken 23 ye

For over a century, astronomers have wondered if there's an extra planet in our Solar System that we haven't been able to detect yet. It seems like we get another "Planet Nine" candidate — formerly known as Planet X, before Pluto was demoted — every few years, and none have been confirmed. But the possibility has never quite been put to bed, either.

A team of astronomers says it has identified a single, slow-moving infrared object that checks all the right boxes for it being the long-theorized ninth planet lurking beyond Neptune. The hunt for Planet Nine—the solar system’s ghostly gravitational troll—is longstanding, and is based on the peculiar clustering of rocky bodies in the Kuiper Belt beyond the orbit of Neptune. This clustering suggests the presence of some faint, massive object. But the team behind the new study took a new approach

When writing functions in TypeScript (and, truthfully, any language that does not support named parameters), you either pass arguments individually ( n params) or group them into a single object. While both are valid, I am yet to find a case were object parameters aren't the better choice. Say you call a function which creates a user: const signup = () => { // ... createUser("John", "Doe", 28, true); // ... }; At a glance, can you tell what each value means?
