One of The Hot, Dense Blobs Deep Inside Earth Has Been Revealed With New Imaging

For the first time, scientists have taken a proper look at an ultra-low velocity zone. These enigmatic pockets of rock sit close to the Earth’s core, about 3,000 kilometers (1,864 miles) below the surface. At that depth they’re obviously difficult to study, but we know they’re there because of the way seismic waves flow through … Read more

NASA Voyager 1 Space Probe From the ’70s Afflicted by Mysterious Glitch

NASA’s 45-year-old Voyager 1 spacecraft is a marvel. It’s cruising along outside our solar system and still staying in touch with Earth. But it’s presented its team with what NASA is calling a “mystery.” It’s operating normally but sending back some odd telemetry data. The issue likely traces to Voyager 1’s attitude articulation and control … Read more

Mars Has Auroras Without a Global Magnetic Field, And We Finally Know How

Earth’s auroras are a glorious wonder, but our planet isn’t the only place in the Solar System where these phenomena can be found. An atmospheric glow, albeit sometimes in invisible wavelengths, has been spotted at every planet except Mercury, and even some moons of Jupiter… and even a comet. But Mars is where it gets … Read more

Ghostly Unseen “Mirror World” Might Be Cause of Cosmic Controversy With Hubble Constant

An unseen ‘mirror world’ of particles that interacts with our world only via gravity may be key to solving the Hubble constant problem, according to new research. According to new research, an unseen ‘mirror world’ of particles that interacts with our world only via gravity might be the key to solving a major puzzle in … Read more

Scientists Discover “Ghost” Fossils – “Completely Unexpected”

The images show the impressions of a collapsed cell-wall covering (a coccosphere) on the surface of a fragment of ancient organic matter (left) with the individual plates (coccoliths) enlarged to show the exquisite preservation of sub-micron-scale structures ( right). The blue image is inverted to give a virtual fossil cast, ie, to show the original … Read more

NASA is suspending all but the most urgent spacewalks after water was found in an astronaut’s helmet following a previous excursion.

NASA is suspending all but the most urgent spacewalks after water was found in an astronaut’s helmet following a March excursion, agency officials said on Tuesday (May 17). NASA will perform an assessment of its extravehicular mobility unit (EMU) spacesuits after water was found in the helmet worn by European Space Agency (ESA) astronaut Matthias … Read more
