Perseid meteor shower to peak on August 12

Perseid meteor shower to peak on August 12

NASA astronomers have predicted that the Perseids, one of the most popular meteor showers of the year, will peak on 12th of August.

While typical rates for the shower are roughly 80 meteors or ‘shooting stars’ per hour, in outburst years like 2016, the rate reaches 150 to 200 meteors per hour.

The Perseid shower’s actual peak is expected to take place around 1 p.m. EDT on 12th of August. It means the night before and the night after will also give good rates.

Astronomers detect stratosphere on a distant exoplanet

A team of American astronomers have discovered evidence for existence of a stratosphere on an exoplanet, a planet outside our solar system.

It may be noted here that a stratosphere is a layer of atmosphere on a planet in which temperature rises with increase in altitude.

The scientists detected the stratosphere on WASP-121b, a planet outside our solar system dubbed a “hot Jupiter,” which is 900 light-years away from Earth.

The Perseid meteor shower, one of the most popular celestial events, is once again garnering attention worldwide as the ‘shooting stars’ are set to peak soon.

Earth is currently whizzing through debris or particles left over from the Comet 109P/Swift-Tuttle, marking the start of the Perseids. Scientists have estimated that the Perseids will peak on 12th of August.

Astronomers catch signal from ‘Exomoon’

Astronomers catch signal from ‘exomoon’

Using the powerful Kepler Space Telescope, a team of NASA astronomers has discovered the first known moon beyond our solar system. The astronomers estimated that the “exomoon” is probably equivalent to Neptune in size and mass, and its host planet equivalent to Jupiter in size but with ten times the mass.

The astronomers couldn’t find any predictions of a Neptune-sized moon in the literature, but Dr. David Kipping, assistant professor of astronomy at Columbia University in New York, noted that nothing prevents one in physics.

Large meteor streaks across Northwest skies

Large meteor streaks across Northwest skies

A number of people reported a bright green streak lasting for several seconds across the night sky in the northwest at around 9:30 p.m. on Saturday. By some accounts, the bright green streak in the night sky lasted for at least 5 seconds, which is a long time for a typical meteor. People from Salem, Oregon to British Columbia and from Tri Cities to Astoria reported seeing it.

ISS returns to its full capacity of six astronauts

ISS returns to its full capacity of six astronauts

The arrival of the three astronauts at the International Space Station (ISS) has once again boosted the orbiting lab back up to its full capacity of six. It is for the first time since April that the ISS has reached its full capacity of six astronauts. The new three-man space crew, one astronaut each from Russia, Italy and the United States arrived at the ISS on Friday for a five-month mission.

China to build Mars simulation base

China to build Mars simulation base

China has revealed plans to build a simulation Mars base in the Qaidam Basin of its Qinghai province in the northwestern part of the country.

Revealing the plans, Chinese authorities said the simulation Mars base will act as an educational experience of future settlements on the Red Planet.

The location of the Qaidam Basin has been selected because the landscape and the climatic conditions there are quite similar to those that are found on the Red Planet. The more than 95,000-square kilometer area is actually a desert with harsh dry conditions.

Russian Soyuz Spacecraft to carry three astronauts to International Space Station

A Russian Soyuz spacecraft carrying three new crew members for the International Space Station (ISS) is all set to launch this Friday, officials have announced.

The Soyuz MS-05 will launch from a launch pad at the Baikonur Cosmodrome in Kazakhstan at 11:41 a.m. EDT Friday (GMT-4; 9:41 p.m. local time).

It will be carrying flight commander Cosmonaut Sergey Ryazanskiy, flight engineers Randy Bresnik of NASA and Paolo Nespoli of the European Space Agency.

Engine for NASA’s SLS Megarocket successfully tested

NASA has successfully test-fired the RS-25 rocket engine for its future megarocket, the Space Launch System (SLS), for nearly 8.5 minutes.

Agency officials announced that the test, which was the third in a row, was conducted on the A-1 Test Stand at NASA’s Stennis Space Center close to Bay St. Louis in Mississippi.

The highly-powerful RS-25 engine will be used to power the upcoming SLS, which is being built for conducting deep space missions.

Astronomers capture Intergalactic Gamma Ray Burst

Astronomers capture Intergalactic Gamma Ray Burst

An international team of astronomers led by Eleanora Troja of the University of Maryland caught a massive star as it died with an immense explosion deep in space.

The blast created a flash of visible light that 31 astronomers from the University of Maryland and Arizona State University and other institutions caught on 25th of June last year, at 6 p.m. ET.
