Black hole study challenges Kerr solution assumptions (Image Credit: Phys.org) Left: Specific realization for the Misner-Sharp mass in Eq. (18) and parameters 𝑀0=10, ℓ=1,𝑣𝑖=−20, 𝑣𝑓=1000, 𝑠1=1, 𝑠2=1/40. The radius of the outgoing shell is set initially at 𝑅(𝑣=30)=5. Right: Misner-Sharp mass 𝑀+(𝑣,𝑅(𝑣)) in the region interior to the outgoing shell for an illustrative example 𝑚(𝑣)=−𝛽[1+𝜀cos(𝜔𝑣)/𝑣]/𝑣𝑝 […]

Learning more about supernovae through stardust (Image Credit: Phys.org) Pair of presolar grains from the Murchison meteorite. Credit: Argonne National Laboratory, Department of Energy Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of […]

SpaceX plans to launch nearly 6,000 pounds (2,700 kilograms) of supplies to the International Space Station (ISS) today (Nov. 4), and you can watch the action live. A Falcon 9 rocket is scheduled to lift off from Pad 39A at NASA’s Kennedy Space Center in Florida today at 9:29 p.m. EST (0129 GMT on Tuesday, […]
SpaceX scrubbed a launch of its Starlink satellites this weekend due to an issue with one of its rockets. The company was scheduled to launch a Falcon 9 rocket containing 23 of its Starlink satellites on Sunday (Nov. 3) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida, but SpaceX […]
Boost for Mars life? Red Planet’s magnetic field may have lasted longer than thought (Image Credit: Space.com) Mars’ magnetic field may have survived 200 million years longer than scientists had thought — crucially, long enough for it to overlap with the presence of liquid water on the surface of the Red Planet. That’s the conclusion […]

Asteroid Apophis Will Endure Quakes and Surface Shifts During 2029 Earth Flyby (Image Credit: Gizmodo-com) A team of astronomers believe that our planet’s gravitational pull could alter the surface of Apophis, a near-Earth asteroid (NEA) set to make a close approach to Earth in five years’ time. Apophis is currently 1.97 astronomical units from Earth—or […]
