Japan’s Akatsuki spacecraft captures gravity wave on Venus

Japan’s Akatsuki spacecraft captures gravity wave on Venus

Not long after entering Venus’ orbit in December 2015, Japan’s Akatsuki spacecraft has captured a really weird atmospheric phenomenon, a gravity wave, in the planet’s upper cloud layer.

Gravity waves are common phenomenon, and their effects are often seen on the clouds and oceans. These waves are caused when an atmosphere or body of water is disturbed. As gravity tries to restore equilibrium, it overshoots and causes a wave effect.

Launch of Japan’s mini rocket SS-520 ends in failure

Launch of Japan’s mini rocket SS-520 ends in failure

Japan’s space efforts suffered a major setback on Sunday when the launch of its miniature SS-520 rocket, which was designed to put a microsatellite into Earth’s orbit, ended in failure.

The Japan Aerospace Exploration Agency (JAXA) confirmed that the SS-520 rocket lifted off successfully at 8:33 a.m. local time and it was on a normal flight path. But ignition of the rocket’s second stage was cancelled by ground controllers after it stopped sending telemetry data.

SpaceX’s Falcon 9 rocket returns to flight

After a gap of several months, SpaceX’s Falcon 9 booster returned to flight on Saturday, Jan. 10th, and successfully launched 10 satellites into Earth’s orbit.

SpaceX announced that a two-stage Falcon 9 rocket lifted off at 12:54 p.m. EST (1754 GMT) from a launch pad at the Vandenberg Air Force Base in California, just a few hundred meters from the scenic coastline of the state.

Two astronauts carry out spacewalk to boost ISS’ power grid

Two astronauts carried out a trouble-free hours-long spacewalk on Friday to complete an upgrade to the International Space Station’s (ISS’) power supply.

The spacewalk was scheduled to last roughly 6.5 hours, NASA astronaut Shane Kimbrough and French astronaut Thomas Pesquet of the European Space Agency (ESA) successfully complted the mission in merely 3.5 hours.

Tillerson questions scientists’ ability to predict effects of increased carbon levels

Tillerson questions scientists’ ability to predict effects of increased carbon levels

Rex Tillerson, President-elect Donald Trump’s choice for secretary of state, recently said that scientists’ ability to predict the effect of increased concentration of greenhouse gases in the atmosphere is “very limited.”

The Moon is a blend of multiple moonlets: study

The Moon is a blend of multiple moonlets: study

Earth's Moon is not a single rock but a blend of multiple moonlets, a new study led by planetary scientist Raluca Rufu of Israel's Weizman Institute of Science suggested.

According to the new study, the silently serene Moon was formed as a result of merger of a number small moonlets or disks of planetary debris produced by multiple objects' collision with Earth.

Monkey caught attempting sex with female deer

Monkey caught attempting sex with female deer

Revealing a rare case of an attempted inter-species mating, researchers on Tuesday posted a video showing a highly unusual behaviour of a male monkey trying to have sex with female deer in Japan.

Sex between animals from different species is really rare and uncommon. However, exceptional cases of sex between creatures from different species are known to occur, mainly in captive and domesticated animals.

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.
