Astronomers say S5-HVs1 ventured close to supermassive black hole before being ejected.

Neutron stars cannot exist.

“The sky was clear—remarkably clear—and the twinkling of all the stars seemed to be but throbs of one body, timed by a common pulse.” —Thomas Hardy.

On June 13, 2012 NASA launched the Nuclear Spectroscopic Telescope Array (NuSTAR) on a mission to study X-rays in what are thought to be the remnants of supernova explosions, called pulsars. NuStar joins other X-ray space telescopes like Chandra and XMM-Newton, except that it is capable of focusing X-rays to a sharp point, enabling it to “see” energies up to 79,000 electron-volts. That capability makes it more than 100 times more powerful than the other observatories.

Theoretically, the universe may be riddled with tunnels through space and time. Two scientists have now proposed a way to detect the existence of a cosmic escape hatch.

Stars explode. But how?

A recent press release asks, “What happens when a star explodes?” The answer, not surprisingly, is, “…the same thing that happens when gas explodes here on Earth.”

The Electric Universe agrees with modern physics: a supernova is an exploding star. However, there is much more to the story that involves plasma. Electricity flowing through plasma creates regions of charge separation isolated by double layers. Could charge separation be the foundation for supernovae?

NASA recently detected a massive thermonuclear explosion coming from outer space.

The culprit seems to be a distant pulsar, the space agency reports, which is the stellar remains of a star that blew up in a supernova but was too small to form a black hole. NASA spotted the burst because it sent out an intense beam of x-rays that got picked up by the agency’s orbital observatory NICER.

There’s a hole in the story of how our universe came to be. First, the universe inflated rapidly, like a balloon. Then, everything went boom.

But how those two periods are connected has eluded physicists. Now, a new study suggests a way to link the two epochs.

Most people think of space as a flat sheet: You travel in one direction, and you end up far from your starting point. But a new paper suggests that the universe may in fact be spherical: If you travel far enough in the same direction, you’d end up back where you started.

Based on Einstein’s theory of relativity, space can bend into different shapes, so scientists assume the universe must be either open, flat, or closed. Flat is the easiest shape to understand: it is how we experience space in our everyday lives, as a plane in which a beam of light would extend off into infinity. An open universe would be saddle-shaped, with a beam of light bending across the curvature. And a closed universe would be a sphere, with a beam of light eventually looping back around it to meet its origin.

In order to tell which shape our universe is, scientists can look at a phenomenon called the cosmic microwave background (CMB). This is the electromagnetic radiation which remains from the Big Bang, also called “relic radiation.” It fills all of space and can be detected with a sufficiently powerful radio telescope.

The XENON experiment recently made a breakthrough in their hunt for dark matter, observing the most rare decay process in the Universe that involves neutrinos.
