For The First Time, a Lone Black Hole Has Been Found Wandering The Milky Way

Like an ancient cardigan, the Milky Way should be absolutely riddled with black holes. According to our best estimates, there should be as many as 10 million to 1 billion stellar-mass black holes out there, drifting peacefully and quietly through the galaxy. There’s just one problem when it comes to counting them: Unless they manage … Read more

Strongest magnetic field did not produce exotic particles called magnetic monopoles

Researchers have used the strongest magnetic field ever measured to search for exotic particles called magnetic monopoles, but they came up empty Physics 2 February 2022 By Leah Crane Accelerator beam pipes at the Large Hadron Collider at CERN near Geneva, Switzerland Daniel Dominguez/CERN The strongest magnetic field ever measured anywhere in the universe has … Read more

Birds Use Earth’s Magnetic Field For ‘Stop Signs’ When They Migrate

Thanks to a combination of sensing the Earth’s magnetic field through vision and an in-built compass that allows them to orient themselves according to magnetic intensity, migratory birds don’t have much trouble finding their way.   Those biological gadgets, known as magnetoreception, allow birds to not only know which direction to head in on their first outbound migration but … Read more

Bird navigation: Slope of Earth’s magnetic field may be ‘stop sign’ for migrating species

Eurasian reed warblers migrate to sub-Saharan Africa each year – and they seem to use the slope of Earth’s magnetic field to judge when they have reached their European breeding grounds Life 27 January 2022 By Alex Wilkins A Eurasian reed warbler Shutterstock / Rafal Szozda Some birds rely on Earth’s magnetic field to navigate and … Read more

The Source of Ghostly Shadows in The Sun’s Atmosphere Could Finally Be Identified

We might finally have an explanation for mysterious shadows of falling material in the atmosphere of the Sun, observed during solar flares. First spotted in 1999, these mysterious streaks of shadow – referred to as “downward-traveling dark voids” – were thought to be related to the magnetic field interactions that trigger solar eruptions. Now, solar … Read more

Two Solar Flares Just Erupted on The Sun, Bringing Coronal Mass Ejections

After a series of eruptions on the Sun, Earth may be in for auroras over the next few days. A sunspot called AR2929 has emitted two solar flares, accompanied by coronal mass ejections. Although neither was directed at Earth, the ejections that are currently blasting through space may deliver glancing blows to our planet’s atmosphere that … Read more

Strong, Sporadic Magnetic Fields Could Explain One of The Moon’s Enduring Mysteries

It’s been half a century since the Apollo missions returned from the Moon, and yet the lunar samples they brought home continue to baffle us. Some of these rocks are more than 3 billion years old and appear to have been formed in the presence of a strong geomagnetic field, like the one on Earth. … Read more

The moon: Magnetic field may have been disrupted by huge sinking rocks

There’s a new explanation for the moon’s former magnetic field, and it involves 60-kilometre-wide slabs of rock sinking through the lunar mantle Space 13 January 2022 By Matthew Sparkes The moon once had a relatively strong magnetic field NASA Moon rocks collected by the Apollo missions sparked a mystery because they showed signs of having formed … Read more

A ‘rogue asteroid field’ almost delays the Valoria 3 analog Mars mission — Commander’s Report: sol 2

Dr. Michaela Musilova is the director of Hawaii Space Exploration Analog and Simulation (HI-SEAS) program, which conducts analog missions to the moon and Mars for scientific research at a habitat on the volcano Mauna Loa. Currently, she is in command of the two-week Valoria 3 Martian mission and contributed this report to’s Expert Voices: … Read more

New Math Research Group Reflects a Schism in the Field

A new organization called the Association for Mathematical Research (AMR) has ignited fierce debates in the math research and education communities since it was launched last October. Its stated mission is “to support mathematical research and scholarship”—a goal similar to that proclaimed by two long-standing groups: the American Mathematical Society (AMS) and the Mathematical Association … Read more
