What Is A Neutron Star?

Neutron stars are created when giant stars die in supernovae and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons. Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun. Born from...

Accretion Of A Giant Planet Onto A White Dwarf Star

The Neptune-sized planet, which orbits an Earth-sized star, is being slowly evaporated by the white dwarf, causing the planet to lose some 260 million tons of material every day. For the first time, astronomers have discovered evidence for a giant planet orbiting...

What If We had Two Suns in The Solar System?

For a long time, this was a purely theoretical question. Over the past decade or so, however, astronomers have found more than a dozen confirmed instances of “circumbinary planets”—that is, planets that orbit around a close double star. A particularly interesting...

Black Holes Are Strange Sure But White Holes Are Mind-Blowing

White holes are black ones in reverse, spewing out matter– and they could give us our first glimpse of the quantum source of space-time. In the textbooks, Gravitation and Cosmology, Nobel prizewinning physicist Steven Weinberg wrote that the existence of black holes...

This Star Just Won't Stop Exploding!

This star has been going nova every year, for millions of years. A nova star is like a vampire that siphons gas from its binary partner. As it does so, the gas is compressed and heated, and eventually, it explodes. The remnant gas shell from that explosion expands outward...

What Happens To Our Brain As We Get Older?

Brain ageing is inevitable to some extent, but not uniform; it affects everyone, or every brain, differently. Slowing down brain ageing or stopping it altogether would be the ultimate elixir to achieve eternal youth. Are there steps, we can take to reduce the rate of decline? At...

Insulin Should Be Cheap. Here’s Why It's Not

When inventor Frederick Banting discovered insulin in 1923, he refused to put his name on the patent. He felt it was unethical for a doctor to profit from a discovery that would save lives. Banting’s co-inventors, James Collip and Charles Best, sold the insulin patent to...

An Afterglow Of GRB That Featured The Highest Energy Photons

Gamma-ray bursts (GRBs) are the most powerful explosions in the cosmos. These explosive events last a fraction of a second to several minutes and emit the same amount of gamma rays as all the stars in the universe combined. Such extreme amounts of energy can only be released...
