Super-Earth Exoplanets May Be Our Best Bet For Finding Life

The Conversation reports that astronomers have been routinely discovering exoplanets orbiting stars outside our own solar system.

This summer, teams at NASA's Transiting Exoplanet Survey Satellite found a number of interesting planets in their parent stars' habitable zones.

This summer, teams at NASA's Transiting Exoplanet Survey Satellite found a number of interesting planets in their parent stars' habitable zones.

Two of these exoplanets are 'super-Earths,' massive planets as much as 70% larger than Earth.

Current projections suggest that super-Earths are the most common type of exoplanet in the Milky Way, accounting for one third of all exoplanets.

Super-Earths possess a number of attributes that make them even more habitable than our normal-sized Earth.

Larger planets are more likely to have more geological activity, which scientists believe promotes biological evolution.

They also have thicker atmospheres that act as an insulating blanket and keep an average temperature around 77 degrees Fahrenheit.

Finally, most super-Earths orbit cool dwarf stars which are far older than our Sun, which means that life there would have had more time to develop.

The Conversation reports that the best chance for finding life on a distant super-Earth will come with the next generation of giant, ground-based telescopes.

Currently still under construction, these telescopes are set to start collecting data by the end of the decade.

NASA Reestablishes Connection With Distant Voyager 1 Space Probe

NASA Reestablishes , Connection With Distant , Voyager 1 Space Probe. The news comes after engineers at the agency worked for months attempting to fix the 46-year-old probe. In December, NASA's Jet Propulsion Laboratory (JPL) said that the probe, now a staggering 15 billion miles away from Earth, was transmitting gibberish code. . On April 23, the JPL announced that the team was once again receiving usable data from the spacecraft. Currently, the probe is only transmitting data regarding the status of the ship's engineering systems. The next step is to enable the spacecraft to begin returning science data again, JPL statement, via 'The Guardian'. 'The Guardian' reports that Voyager 1 has been in operation for nearly half a century after launching in 1977 with the goal of studying Jupiter and Saturn. In August of 2012, Voyager crossed into interstellar space, becoming the first human-made object to leave the solar system. The probe is currently traveling at a staggering 36,800 miles per hour through space. NASA plans to collect data from the two Voyager spacecraft for a few more years, but the space agency expects to lose contact with the probes within the next decade

Dubai Floods: NASA posts pics of flooded UAE areas after 6 billion cubic metres of rain| Oneindia

NASA has unveiled striking images capturing the extensive flooding in the UAE following the recent torrential rainfall. Describing it as a "slow-moving storm," NASA highlighted the unprecedented deluge that inundated the Gulf states, surpassing a year's worth of rainfall in some regions. According to the UAE's meteorological department, the country received a staggering 6.04 billion cubic metres of rain last week, nearly equivalent to its annual precipitation of 6.7 billion cubic metres. This remarkable event underscores the magnitude of the weather phenomenon that swept across the region. #DubaiFloods #UAEFloods #NASAImages #FloodedUAE #RainInUAE #UAEWeather #FloodMonitoring #NASAData #UAEEnvironment #ClimateChange ~PR.152~ED.155~GR.123~HT.318~

Astronomers May Have Solved the Mystery Surrounding Blue Supergiant Stars

Astronomers May Have Solved, the Mystery Surrounding , Blue Supergiant Stars. 'Newsweek' reports that astronomers now believe that some of the brightest and hottest stars in existence may be the result of collisions between two other stars. Scientists have long sought to determine how these intensely bright stars, known as blue supergiants, are formed. . According to a new paper published by 'The Astrophysical Journal Letters,' scientists suggest that blue supergiants are the result of two binary stars merging into one. Blue supergiants, which are about 16 to 40 times the mass of our sun, are some of the most massive stars in the universe. . Their intensely hot surface temperatures are often two to five times hotter than our sun and over 10,000 times more luminous. 'Newsweek' reports that the latest research looked at 59 early B-Type blue supergiant stars in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way galaxy. . We simulated the mergers of evolved giant stars with their smaller stellar companions over a wide range of parameters, taking into account the interaction and mixing of the two stars during the merger, Athira Menon, study author and an astrophysicist at the Instituto de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'. The newly-born stars live as blue supergiants throughout the second longest phase of a star's life, when it burns helium in its core, Athira Menon, study author and an astrophysicist at the Instituto de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'. The results obtained explain why blue supergiants are found in the so-called 'evolutionary gap' from classical stellar physics, a phase of their evolution where we would not expect to find stars, Artemio Herrero, study co-author and a researcher at the Instituto de Astrofísica de Canarias (IAC) in Spain, via 'Newsweek'. The team reportedly hopes to continue its investigation into the role that merging stars could play in the formation of galaxies, as well as how blue supergiants form neutron stars or black holes. .
