Probing deeper into origins of cosmic rays

Cosmic rays are high-energy atomic particles continually bombarding Earth's surface at nearly the speed of light. Our planet's magnetic field shields the surface from most of the radiation generated by these particles. Still, cosmic rays can cause electronic malfunctions and are the leading concern in planning for space missions.

Astronomy and Space news

New energetic pulsar discovered in the Small Magellanic Cloud

Using ESA's XMM-Newton spacecraft, an international team of astronomers has detected a new energetic rotation-powered pulsar in the Small Magellanic Cloud (SMC). The newly found pulsar, designated PSR J0058–7218, appears to be the most energetic pulsar so far discovered in the SMC. The finding is detailed in a paper published May 17 on

Mapping the local cosmic web: Dark matter map reveals hidden bridges between galaxies

A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map, developed using machine learning by an international team including a Penn State astrophysicist, could enable studies about the nature of dark matter as well as about the history and future of our local universe.

Prebiotic ethanolamine found in a molecular cloud near the center of the Milky Way

An international team of researchers has found evidence of prebiotic ethanolamine (NH2CH2CH2OH) in a molecular cloud near the center of the Milky Way galaxy. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the amino alcohol and why they believe it could have contributed to the development of life on earth.

Does the Milky Way move like a spinning top?

An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) Žofia Chrobáková, a doctoral student at the IAC and the University of La Laguna (ULL), and Martín López Corredoira, questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect. The results have just been published in The Astrophysical Journal.

Who's an astronaut as private spaceflight picks up speed?

As more companies start selling tickets to space, a question looms: Who gets to call themselves an astronaut?

Why the sun's atmosphere is hundreds of times hotter than its surface

The visible surface of the sun, or the photosphere, is around 6,000°C. But a few thousand kilometers above it—a small distance when we consider the size of the sun—the solar atmosphere, also called the corona, is hundreds of times hotter, reaching a million degrees celsius or higher.

Do supermassive black holes merge to form binary systems?

At the center of most galaxies are black holes so massive—up to several billion times the mass of our sun—that they have earned the descriptor "supermassive." Compare this to your run-of-the-mill stellar-mass black hole, a measly 10 to 100 times our sun's mass. Understanding these supermassive black holes will help astronomers understand the origin and evolution of galaxies. One open question is whether they can form binaries.

Candid cosmos: eROSITA cameras set benchmark for astronomical imaging

Recently, the eROSITA (extended Roentgen Survey with an Imaging Telescope Array) X-ray telescope, an instrument developed by a team of scientists at Max-Planck-Institut für Extraterrestrische Physik (MPE), has gained attention among astronomers. The instrument performs an all-sky survey in the X-ray energy band of 0.2-8 kilo electron volts aboard the Spectrum-Roentgen-Gamma (SRG) satellite that was launched in 2019 from the Baikonur cosmodrome in Kazakhstan.

PUNCH mission passes important milestone

On May 20, 2021, the Polarimeter to UNify the Corona and Heliosphere (PUNCH) mission achieved an important milestone, passing NASA's Preliminary Design Review (PDR) of its spacecraft and payload experiments. Southwest Research Institute is leading PUNCH, a NASA Small Explorer (SMEX) mission that will integrate understanding of the Sun's corona, the outer atmosphere visible during total solar eclipses, with the "solar wind" that fills the solar system.

Team builds first hacker-resistant cloud software system

Whenever you buy something on Amazon, your customer data is automatically updated and stored on thousands of virtual machines in the cloud. For businesses like Amazon, ensuring the safety and security of the data of its millions of customers is essential. This is true for large and small organizations alike. But up to now, there has been no way to guarantee that a software system is secure from bugs, hackers, and vulnerabilities.

More efficient lidar sensing for self-driving cars

If you see a self-driving car out in the wild, you might notice a giant spinning cylinder on top of its roof. That's a lidar sensor, and it works by sending out pulses of infrared light and measuring the time it takes for them to bounce off objects. This creates a map of 3D points that serve as a snapshot of the car's surroundings.

Two new attacks break PDF certification

A security issue in the certification signatures of PDF documents has been discovered by researchers at Ruhr-Universität Bochum. This special form of signed PDF files can be used, for instance, to conclude contracts. Unlike a normal PDF signature, the certification signature permits certain changes to be made in the document after it has actually been signed. This is necessary to allow the second contractual party to also sign the document. The team from the Horst Görtz Institute for IT Security in Bochum showed that the second contractual party can also change the contract text unnoticed when they add their digital signature, without this invalidating the certification. The researchers additionally discovered a weakness in Adobe products that enables attackers to implant malicious code into the documents.
