After successful missions to the Moon, Mars and even distant interstellar space, NASA now plans to launch the Solar Probe Plus mission to the Sun, which is around 149 million kilometres from the Earth. Mankind has forever pushed the boundaries in attempting to achieve the impossible, and it has always been assumed that getting close to the sun was a recipe for death.
We live in the sun's atmosphere! It would be the closest manmade object to the sun ever if the mission is successful, and it will be seven times closer than any spacecraft has ever come to the sun. Further, this doesn't sit well with the general notion of "the farther you go from the source of heat, the colder it gets" and that's why it a big puzzle.
Researchers have tried to figure out these three enduring mysteries Christian said, but "the trouble is we're 93 million miles away, and things get smeared out in a way that makes it hard to tell what's happening at the sun".
Two of the transformative advances in our understanding of the Sun and its influence on the solar system were the discovery that the corona is several hundreds of times hotter than the visible solar surface (the photosphere) and the development-and observational confirmation-of the theory of the corona's supersonic expansion into interplanetary space as a "solar wind".
The answers to these questions can be obtained only through in-situ measurements of the solar wind down in the corona. He wonders if this suggests that something, perhaps solar winds are coming off the sun faster than the comet was moving.
Scientists are hoping to use the probe to gather data to help forecast space weather events that affect Earth, like solar flares and storms that knock out communications on Earth and can cause quite a bit of damage.
The National Aeronautics and Space Administration (NASA) is mulling over sending its first robotic spacecraft to the Sun, next year.
The mission may also ascertain why the Sun occasionally emits high-energy particles that are a danger to unprotected astronauts and spacecraft.
NASA has designed an 11.4 centimetres carbon-composite shield, which is created to withstand temperatures outside the spacecraft of 1,370 degrees Celsius.
The probe will also have special heat tubes known as thermal radiators, created to radiate any heat that permeates the heat shield so as to protect the sensitive instruments inside. If everything works properly, the probe should maintain room temperature inside, and be able to beam back data.
Unlike landing probes on Mars and Moon, scientists can not land a probe on the Sun, but they will try to make the closest approach to the Sun while keeping the spacecraft alive.
The spacecraft will also be equipped with protection from solar radiation, which poses a threat to its memory and electrical circuits.
Scientists discover seven exoplanets the size of earth
The first exoplanet was discovered in 1988; since then, to date ( February 22, 2017 ) some 3, 584 exoplanets have been detected. The planets orbit a star called Trappist-1, which is about 40 light years away from Earth, according to the New York Times .

Kim Jong Nam was estranged from his homeland and mostly lived in the semi-autonomous Chinese territory of Macau. The Trump administration sees combating North Korea as a potential area of cooperation with Beijing.
Since Lee assumed a bigger role, Samsung promised to inject the company's top-down hierarchy with a nimble, startup-like attitude. The prosecutors first sought to arrest Lee in January, but a judge turned down that request, citing a lack of evidence.
He hinted that Mexico might seek to challenge Trump's move at the United Nations or in other global bodies. But this is not the first time the month-old Trump administration has diplomatically snubbed the Mexicans.
The Nets were reportedly "determined" to get a first for Bogdanovic, who is set to be a restricted free agent. Washington signed the 27-year-old Nicholson to a four-year deal in free agency but have played him sparingly.
She was showing the signs: pacing, "star gazing", waxing of the teats, irritability, anxiety, according to zoo owner Jordan Patch. The baby is expected to be born sometime in the next few days. "April the giraffe is expecting a calf".
After 12 months, they found that the testosterone group had better bone density and a reduced risk of developing anaemia. The first published research from the TTrials past year reported on some of the benefits to testosterone treatment.
His presence alone helped Golden reach a career-high in sacks and defensive tackle Calais Campbell achieve eight sacks. Jones remains one of the league's premiere pass-rushers and is nearly certain to be back in Arizona next season.
Democrats called for an independent investigation into Trump's Russian Federation ties and urged Republicans to join them. Democrats are also asking that the findings of the Senate Intelligence Committee's investigation be made public.

Pediatricians warn about dangers of pot use by kids
With regards to the effects of medical marijuana on children and teens, solid research is still lacking. However Ryan warned that today's marijuana is much more potent, and therefore potentially more risky.
'Doubt' Pulled From CBS Schedule
While the show received largely positive reviews, mostly for its acting rather than storylines, the rating just weren't there. Katherine Heigl and Laverne Cox's new show Doubt has been pulled from the CBS schedule after only airing two episodes.
Jamie Chung to Play Blink in Fox's Marvel Pilot From Bryan Singer
Chung appeared as Mulan on ABC's Once Upon a Time and is set to portray a recurring role on the upcoming season of Casual in Hulu. This would allow alternate versions of popular X-Men characters-maybe played by other actors-who aren't too big to do a TV show.
How this flu season stacks up to past seasons: 5 key metrics
"Influenza vaccines are effective at reducing the risk of a person getting the flu and having to go to the doctor by about half". Children under age 5, adults 65 and older, pregnant women and people with certain medical conditions are most at risk.
