Large Object From Interstellar Space Detected Heading Toward Center of Solar System

futurism.com Unknown 2026-02-06 16:37:47

A new interstellar object has been spotted careening into the solar system at an extremely unusual trajectory. If its interstellar origins were to be confirmed, it'd only be the third of its kind spotted in the solar system in history. An oblong interstellar object, dubbed 'Oumuamua, was first discovered in 2017, while comet 2I/Borisov was detected in 2019. The latest addition, provisionally named A11pl3Z, has a highly unusual trajectory, leading astronomers to believe it may have also origina

Astronomers may have found a third interstellar object

arstechnica.com Unknown 2026-02-07 12:38:27

There is a growing buzz in the astronomy community about a new object with a hyperbolic trajectory that is moving toward the inner Solar System. Early on Wednesday, the European Space Agency confirmed that the object, tentatively known as A11pl3Z, did indeed have interstellar origins. "Astronomers may have just discovered the third interstellar object passing through the Solar System!" the agency's Operations account shared on Blue Sky.

The provenance memory model for C

In this article, I will try to explain what this is all about, namely on how a provenance model for pointers interferes with alias analysis of modern compilers. For those that are not fluent with the terminology or the concept we have a short intro what pointer aliasing is all about , a review of existing tools to help the compiler and inherent difficulties and then the proposed model itself . At the end there is a brief takeaway that explains how to generally avoid complications and loss of opt

Cell Towers Can Double as Cheap Radar Systems for Ports and Harbors (2014)

news.ycombinator.com Ian Chant 2026-02-13 14:48:12

How do you see ships without a pricey radar system? The question has troubled seaports around the world as they work to improve security. Without radar installations, it can be hard for port employees to detect small ships like those employed by pirates or by the terrorists who attacked the USS Cole in 2000. A team of researchers in Germany can now offer security teams a new option, though: putting existing cellular towers to work as quick and dirty radar systems. Developed at the Fraunhofer In

Parsing JSON in Forty Lines of Awk

news.ycombinator.com Mohamed Akram 2026-02-13 08:23:48

JSON is not a friendly format to the Unix shell — it’s hierarchical, and cannot be reasonably split on any character (other than the newline, which is not very useful) as that character might be included in a string. There are well-known tools such as jq that let you correctly parse JSON documents in the shell, but all require an additional dependency. Another option is to use Python, which is ubiquitous enough that it can be expected to be installed on virtually every machine, and for new proje

Assembly Theory of Time

news.ycombinator.com Unknown 2026-02-21 17:41:02

If the lineages are followed back beyond the origin of life on Earth to the origin of the universe, it would be logical to assume that the memory of the universe was lower in the past, which means that the universe's ability to generate objects of high Assembly is limited by its size in time. Some objects are too large in time to come into existence in intervals that are smaller than their assembly index. For complex objects such as computers to exist in our universe, many other objects had to f

NASA Satellite That’s Been Dead for 57 Years Sends Mysterious Signal to Earth

gizmodo.com Passant Rabie 2026-02-23 08:05:27

A little over a year ago, scientists in Australia picked up a brief burst of electromagnetic radiation. The pulse was so strong that it eclipsed all other signals coming from the sky, but its origins were unknown. After digging through the data, the team discovered that the source wasn’t a distant celestial object but rather a zombie satellite left to orbit Earth with no purpose. NASA’s Relay-2 launched on January 21, 1964, two years after its predecessor, Relay-1, was sent to orbit. The pair w

How Hourglass Vision Transformers Are Redefining Camouflaged Object Detection

computer.org Enrique Quezada 2026-03-04 16:58:20

Introduction While camouflage gives wildlife and military vehicles a strategic survival advantage, it poses challenges, both for human and computer vision systems. It is difficult enough to detect objects designed to blend with their environments, but when the objects have blurry edges, the detection process is even more problematic. However, in a paper written for the 2025 IEEE/CVF Winter Conference on Applications of Computer Vision (WACV), Jinpeng He, Biyuan Liu, and Huaixin Chen of the Uni

Object personification in autism: This paper will be sad if you don't read (2018)

news.ycombinator.com White Rc Remington A 2026-03-11 02:34:48

Object personification is the attribution of human characteristics to non-human agents. In online forums, autistic individuals commonly report experiencing this phenomenon. Given that approximately half of all autistic individuals experience difficulties identifying their own emotions, the suggestion that object personification may be a feature of autism seems almost paradoxical. Why would a person experience sympathy for objects, when they struggle to understand and verbalise the emotions of ot

How fast can the RPython GC allocate?

news.ycombinator.com Cf Bolz-Tereick 2026-03-11 22:55:09

While working on a paper about allocation profiling in VMProf I got curious about how quickly the RPython GC can allocate an object. I wrote a small RPython benchmark program to get an idea of the order of magnitude. The basic idea is to just allocate an instance in a tight loop: class A ( object ): pass def run ( loops ): # preliminary idea, see below for i in range ( loops ): a = A () a . i = i The RPython type inference will find out that instances of A have a single i field, which is an i

Are Those Viral ‘Cooling Blankets’ for Real?

wired.com Rhett Allain 2026-03-14 04:00:00

If you spend much time on the internet, you will see the same things pop up again and again. For me, it's these “cooling blankets” that people talk about on social media. I mean, it sounds great for summer—just like a blanket that warms you up but in reverse. Sadly, these products don’t do what they claim. They might be breathable so they don’t make you as hot as an ordinary blanket would, but you’d still be cooler with no blanket at all. However, there is hope. Someone has created a real cooli

Man Wakes Up, Finds That Large Chunk of SpaceX Rocket Has Crashed Into His Garden

A Polish man named Adam Borucki made an unusual discovery in his backyard after waking up one day: the purported remains of a second stage of a SpaceX Falcon 9 rocket. As the UK tabloid The Daily Mail reports, Borucki reported the "large object about [five by three feet] in size" to the local police. "We are investigating how the object ended up in this location, but the important thing is that no one was harmed," police spokesman Andrzej Borowiak told the tabloid. It seems likely that the ob
