Reykjavik Council switches off city lights to provide clear view of Northern Lights to residents

On Wednesday night, Reykjavik council switched off the lights in the city centre and many other districts from 22:00 local time. Main aim behind the move was to lessen the light pollution so that the capital's residents are able to enjoy the Aurora Borealis, one of the most impressive views of the sky.

Milky Way is not spiral-shaped: Study

Milky Way is not spiral-shaped: Study

A research team has come up with the clearest map of the Milky Way. During the process of producing the map, the scientists have come to know that our solar system might be bigger than what was thought earlier.

Till now it is assumed that our galaxy is shaped like a disk, but there is no consensus on its exact structure. One thing on which scientists agree is that Milky Way has four major arms of star, gas and dust spiraling out from its center.

SNC will fly UN’s first-ever space mission to low-earth orbit in 2021

SNC will fly UN’s first-ever space mission to low-earth orbit in 2021

Sierra Nevada Corporation (SNC) is going to fly the United Nations’ first-ever space mission. SNC and the United Nations Office for Outer Space Affairs (UNOOSA) have joined hands for a two-week robotic mission to low-earth orbit in 2021.

For the mission, SNC’s Dream Chaser spacecraft will be used. UNOOSA Director Simonetta Di Pippo said that one of the main responsibilities of the organization is to promote international cooperation when it comes to peaceful use of outer space.

New details on formation and structure of Pluto’s Sputnik Planum

New revelations have been made with regard to the formation and structure of Sputnik Planum, Pluto’s frozen heart.The research paper published in the journal Nature has suggested that the deep basin became filled with deposits of nitrogen that turned into condensed form due to Pluto’s atmosphere and resulted into the nitrogen ice glacier covering the area.

With the help of data from the New Horizons, the researchers have come to know that atmospheric pressure at the basin of Sputnik Planum is higher than on the surface and terrain surrounding the surface.

Mercury continues to be tectonically active, suggests NASA’s MESSENGER probe data

Mercury continues to be tectonically active, suggests NASA’s MESSENGER probe data

Data gathered from NASA’s MESSENGER probe has unveiled that Mercury is still tectonically active similar to earth. The latest finding has challenged the previous beliefs that Mercury has now been inactive.

The probe was able to gather this vital information during its last 18 months. At that time MESSENGER was orbiting at a lower altitude hence collecting much more detailed high-resolution images than it has received earlier.

Scientists want to find more about Jupiter’s moon Europa

Scientists want to find more about Jupiter’s moon Europa

Since the time NASA has announced that it will make an important announcement about Jupiter’s moon Europa, interest level in the special moon has increased even more. Europa has always been a topic of search among scientists.

They have come to know many interesting things about Europa, but some questions remain to be answered. NASA believes that most probably Europa is having a big ocean filled with salty, liquid water below its icy surface.

China officially launches world’s largest telescope FAST

China officially launches world’s largest telescope FAST

Sunday witnessed the official opening of the world’s largest radio telescope known as Five-hundred-meter Aperture Spherical Telescope (FAST). The telescope has been named after its diameter, which is at 500 meters. The telescope powered with latest technology is 195 meters wider than the second largest telescope.

The telescope will be used for the observation of pulsars and exploration of interstellar molecules and interstellar communication signals. Authorities concerned have shared that FAST will study interstellar molecules so as to know how galaxies evolve.

NASA to disclose about surprising activity on Jupiter’s moon Europa

NASA to disclose about surprising activity on Jupiter’s moon Europa

NASA is expected to release details about suspected subsurface ocean on Jupiter’s moon Europa on Monday. Some have been speculating that the new observed activity could be a sign of the discovery of alien life in our solar system.

The US space agency has organized a press briefing for next Monday, which would be broadcasted on a live video stream. At the event, NASA would publicize about the surprising activity by showing images taken by Hubble space telescope.

Falcon 9 rocket explosion investigation: Large breach in cryogenic helium system detected

Falcon 9 rocket explosion investigation: Large breach in cryogenic helium system detected

Finally SpaceX has come to know what resulted into its Falcon 9 rocket explosion. During the investigation, the company has found a ‘large violation’ in the launcher’s upper stage helium pressurization system.

The breach resulted into destruction of the booster as well as its $200 million satellite payload.SpaceX has been carrying out the investigation with the help from government and industry experts. Now, their next step is to know what resulted into the breach.

Pluto’s subsurface ocean 100 kilometers deep and as salty as Dead Sea: Study

Pluto’s subsurface ocean 100 kilometers deep and as salty as Dead Sea: Study

Since the time NASA’s New Horizons spacecraft has passed by Pluto, it is being suspected that the dwarf planet has a liquid ocean underneath its icy shell. A latest research has come up with new estimations on how thick liquid layer could be.

Study’s lead researcher Brandon Johnson from Brown University said that there is a great possibility that more than 100 kilometers of liquid water is present beneath Pluto’s surface. The study also suggests about the ocean’s composition and also estimated that the salt level is equivalent to that of the Dead Sea.
