All stars are born in pairs: Research

All stars are born in pairs: Research

Our sun had a twin, though not an identical twin, when it was born nearly 4.5 billion years ago, a team of researchers from UC Berkeley and the Harvard University’s Smithsonian Astrophysical has suggested.

A new analysis of available data by theoretical physicist Steven Stahler of UC Berkeley and astronomer Sarah Sadavoy from the Smithsonian Astrophysical Observatory suggested that all stars are born in pairs.

NASA scientists detect barrier around Earth

NASA scientists detect barrier around Earth

NASA’s Van Allen probes have revealed human activities are not having physical and chemical impacts on Earth’s environment, but also on radio frequencies extending out into space.

After analyzing data captured by the probes, NASA scientists concluded that very low frequency (VLF) radio communications make interactions with particles in space, forming an artificial barrier that can block high-energy particle rays from space.

VLF communications are mainly used to communicate with submarines across massive distances in the ocean from very powerful ground stations.

DSCOVR camera captures mysterious light flashes: NASA

DSCOVR camera captures mysterious light flashes

The powerful camera on board NASA’s Deep Space Climate Observatory (DSCOVR) has captured hundreds of flashes of light coming from above our planet’s surface that scientists say are caused by sunlight reflecting off minute ice particles.

Launched in 2015, DSCOVR is an Earth and space weather satellite. Its camera captured the flashes of light that occurred hundreds of times over the extent of a year.

The eagle-eyed instrument captures images of Earth almost hourly from a location between the plant and its host star.

Astronomers detect water in Neptune-sized exoplanet’s atmosphere

Astronomers detect water in Neptune-sized exoplanet’s atmosphere

Astronomers have detected lots of water in the atmosphere of HAT-P-26b, a Neptune-sized exoplanet that is located far outside of our solar system.

Discovered in 2011 and orbiting a sun that is twice as old as our own host star, HAT-P-26b is equivalent in size as Neptune, which has a hydrogen-helium atmosphere. However the exoplanet is warmer than Neptune as it orbits its host star more closely than Neptune does.

SpaceX Falcon 9 set to carry Inmarsat-5 F4 satellite into space

SpaceX Falcon 9 rocket is all set to launch a communications satellite for Inmarsat of London from the Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center (KSC) on coming Monday, 15th of May.

The private-sector space firm is targeting a fifty-minute launch window that will open at 7:20 p.m. EDT or 23:20 GMT tomorrow.

NASA astronauts conduct 200th spacewalk

NASA astronauts conduct 200th spacewalk

NASA astronauts Peggy Whitson and Jack Fischer floated outside the International Space Station (ISS) on Friday, setting a new milestone by successfully conducting 200th spacewalk.

Whitson and Fischer’s spacewalk was shortened by an equipment water leakage, they the duo managed to replace a faulty electronics box. They wasted no time removing the faulty electronics box, and placing a new unit.

NASA rules out astronauts on first flight of super-massive rocket

NASA rules out astronauts on first flight of super-massive rocket

Putting a crew on board the first flight of the Orion capsule atop the super-massive Space Launch System (SLS) rocket would not be feasible because of immense safety costs, a NASA working group has concluded.

The first flight of the super-massive rocket, which is being seen as the first step in the United States’ return to human space exploration, has been scheduled to take place sometime in 2019.

NASA usually tests new rockets first without a crew, given numerous safety risks associated with such space vehicles.

NASA’s new Mars plan includes yearlong mission to the Moon

NASA has revealed a new plan in which a group of astronauts may spend around a year in orbit around the Moon in the late 2020s as part of its broader plan to send humans to Mars a decade later.

Greg Williams, deputy associate administrator for policy & plans in NASA’s Human Exploration & Operations Mission Directorate, revealed the plan at the Humans to Mars Summit in Washington D.C.

NASA releases video starring spacewalking astronauts

NASA releases video starring spacewalking astronauts

U.S. space agency NASA has released a stunning ‘action cam’ video of a spacewalk on the International Space Station (ISS), showing what exactly takes place after an astronaut steps out of the orbiting lab.

The renowned space agency shared the footage, which was captured by Pesquet on 24th of March, by posting it on Google’s video-sharing service YouTube.

The footage essentially shows two astronauts conducting a spacewalk outside of the orbiting lab. It also presents a breath-taking view of our planet from an altitude of 250 miles.

SpaceX to start testing high-speed satellite broadband later this year

SpaceX to start testing high-speed satellite broadband later this year

SpaceX has confirmed that it is working on a plan to establish a global broadband internet constellation and start on-orbit tests for that as soon as later this year.

Nearly a couple of years ago, SpaceX Chief Executive Elon Musk had revealed the company’s intention to create an internet constellation, consisting of thousands of satellites in low-Earth orbit (LEO) to provide customers with 1 Gbps broadband.
