Methane drives sea level rise for centuries: study

Methane drives sea level rise for centuries: study

Even greenhouse gases like methane that do not last long in the atmosphere can drive sea level rise for centuries, a team of researchers from Simon Fraser University and MIT warned.

MIT professors Susan Solomon and Daniel Gilford teamed up with Kirsten Zickfeld of Simon Fraser University for the new study, which suggested that though the atmospheric warming caused by greenhouse gases like methane may taper off quickly after their emissions are stopped, their effects in the oceans are long-lived.

Researchers discover two black holes in our cosmic backyard

Researchers discover two black holes in our cosmic backyard

Using the powerful Nuclear Spectroscopic Telescope Array (NuSTAR), NASA scientists have discovered two gas-enshrouded super-massive black holes, lurking at the centers of nearby galaxies.

Researcher Ady Annuar, of Durham University in the U.K., said the two black holes remained hidden from astronomers until recently, despite their relatively close proximity to the Milky Way. He added that it’s like two monsters are hiding under your bed.

Binary star system predicted to merge & explode in five years

Binary star system predicted to merge & explode in five years

A binary star system in the constellation Cygnus will merge and explode in five years, a team of astronomers from Calvin College, Apache Point Observatory and the University of Wyoming predicted.

Larry Molnar of Calvin College had originally predicted the potential merger and explosion of the KIC 9832227 binary star system in 2015. Now, he has confirmed that his theory will become a reality by 2022.

NASA to send two probes to explore Jupiter’s Trojan asteroids

NASA to send two probes to explore Jupiter’s Trojan asteroids

NASA has announced two new space missions to investigate two strange asteroids that share an orbit with Jupiter, the largest planet in our solar system.

Announced as part of its Discovery Program, the two space missions, called Psyche and Lucy, will explore two of the solar system’s most strange space rocks. The spacecraft “Lucy” will explore the so-called Trojan asteroids, and the spacecraft Psyche will explore a huge metallic asteroid known as 16 Psyche.

Astronomers trace burst of cosmic light back to its home galaxy

Astronomers trace burst of cosmic light back to its home galaxy

An international team off astronomers has directly traced an incredibly intense and bright burst of cosmic radio waves, dubbed fast radio burst (FRB), back to its home galaxy.

The bright burst of cosmic light, FRB 121102, was first discovered in 2007, and a new study suggested that it had originated from inside a dwarf galaxy, around 3 billion light years away from our planet.

Dinosaurs took months to hatch out of their eggs: researchers find

Dinosaurs took months to hatch out of their eggs: researchers find

Some species of dinosaurs were not able to venture off in search of food or even to flee predators as long as they were incubating their eggs, and some eggs took months to hatch, a new research suggested.

Using a new technique on some rare fossils of unhatched dinosaur eggs allowed Paleontologist Gregory M. Erickson of Florida State University and colleagues to determine that some dinosaur eggs took 6 months and even longer to hatch.

SpaceX to attempt Falcon 9 launch again this weekend

SpaceX to attempt Falcon 9 launch again this weekend

Roughly three months after suffering a devastating Falcon 9 rocket explosion that destroyed a $200 million Facebook satellite as well, SpaceX is going to make another attempt this weekend.

The Elon Musk-led space firm announced the plans for making another attempt as part of its report on its Falcon 9 rocket explosion that occurred on 1st of September at Cape Canaveral, Florida.

In the report, SpaceX said that its engineers have fixed the glitch that had caused the explosion, allowing the company to make another attempt on coming Sunday.

Merely 7,100 cheetahs left in the world: report

Merely 7,100 cheetahs left in the world: report

Merely 7,100 cheetahs (Acinonyx jubatus), the fastest animal on our planet, are left in the entire world, the Zoological Society of London (ZSL) and the Wildlife Conservation Society (WCS) warned in its latest report.

Study authors also wrote that cheetahs have now been driven out of 91 per cent of their historic range. Now, there are fewer than 50 Asiatic cheetahs left in the world, and all of them are in an isolated part of Iran.
