A Star Is Racing at 8.5% Light Speed, Offering a Potential Test of Einstein’s Theory

Leave a Comment / Aerospace, Space & Environment /

Things can become truly bizarre in the extreme conditions at the center of the Milky Way galaxy. And by bizarre, we mean phenomena that are almost impossible to comprehend. At the heart of the galaxy lies a supermassive black hole known as Sagittarius A*, with a mass roughly 4.3 million times greater than that of […]

USP researchers develop a method to detect stars that swallowed planets

Leave a Comment / Aerospace, Space & Environment /

An international research team led by scientists at the University of São Paulo (USP) has developed a new technique for identifying stars that have consumed planets in their systems. The method focuses on changes in the levels of beryllium, a relatively uncommon chemical element, offering a promising new way to investigate how planetary systems evolve.

Mars’ Doomed Moon Could Conceal Clues to an Ancient Catastrophic Event

Leave a Comment / Aerospace, Space & Environment /

Phobos has orbited Mars for billions of years, yet scientists have not determined exactly how the small moon formed. One theory suggests that Mars captured Phobos as an asteroid, while another proposes that it formed from debris thrown into space when a massive object slammed into the Martian surface. Solving the mystery may depend on

Japan plans a massive solar ring around the Moon to power Earth

Leave a Comment / Aerospace, Space & Environment /

The idea of collecting solar energy in space has evolved from science fiction into a serious engineering concept. More than a decade ago, Japan’s Shimizu Corporation unveiled plans for the Luna Ring, a continuous band of solar panels encircling the Moon’s equator. The proposed structure would stretch about 6,800 miles, enabling it to capture sunlight

Researchers Uncover Bacteria That Consume Uranium in an Old Soviet Mine

Reusability, Space & Environment /

One of the world’s largest uranium mining operations, the Wismut GmbH Schlema-Alberoda mine in the former Soviet-controlled East Germany, left a lasting environmental burden after decades of extraction. However, scientists have discovered that the contaminated water filling the abandoned mine may contain a natural answer to the pollution problem. Microorganisms that have adapted to the

New Simulations Reveal Earth’s Strongest Ocean Current

Aerospace, Space & Environment /

New climate simulations suggest that the world’s most powerful ocean current emerged only after a unique combination of geological and atmospheric changes came together, rather than forming suddenly. The Antarctic Circumpolar Current (ACC) is the strongest ocean current on Earth, flowing clockwise around Antarctica. About five times more powerful than the Gulf Stream, it links

Earth’s underground fungal network is so vast that, if stretched out, it could reach distant star systems

Aerospace, Space & Environment /

Scientists have mapped Earth’s vast underground fungal network, revealing it is so extensive that, if stretched into a single line, it could reach other star systems and span a significant portion of the Milky Way. The study, published in Science, focused on arbuscular mycorrhizal fungi—microscopic organisms that form a hidden framework in soil. These fungi

Asteroid 1997 NC1 is expected to make a close approach to Earth at the end of June

Aerospace, Space & Environment /

Toward the end of June, Earth is expected to have a close encounter with asteroid 152637, also known as 1997 NC1, which will make its nearest approach in more than 400 years on June 27. The asteroid will pass about 2.56 million kilometers from Earth—a distance astronomers consider close. Reports from IFL Science suggest this
