An extrasolar planet approximately 117 light years away from earth has been discovered by a team of astronomers. It is believed to be the most eccentric planet in the observable universe, as per the team led by astronomer Stephen Kane from San Francisco State University.

Kane and his team also claimed that they detected a signal of reflected light from the extrasolar planet, dubbed as HD 20782. They revealed their discovery last month in The Astrophysical Journal.

Space enthusiasts with their telescopes pointing towards sky are going to get a rare celestial treat in the form of two comets that are scheduled to zip past earth this week. One of the comets will be closer to earth than any other comet since decades.

The bigger comet, as 252P/LINEAR, is more than 700 feet in size. The solar system body surrounded by green cloud of gas will make its closest flyby of earth on Monday at around 5:14 am. During the historic flyby, the comet will come within 3.3 million miles of our planet.

Researchers have found a new butterfly species which they believe is the only kind of butterfly endemic to Alaska. The butterfly, called the Tanana arctic, was misidentified for over six decades, as per the researchers.

The butterfly species could be spotted in Tanana-Yukon River Basin region. Researchers think the butterfly could change their opinion on global warming as it responds very quickly to climate change. The new Alaskan butterfly species may help study changes in the arctic ecosystem, said Andrew Warren, a butterfly expert from the University of Florida in Gainesville and an author of a new paper on the discovery.

Researchers at the University of Miami’s Miller School of Medicine claimed that healthy heart leads to healthy brain. The research team conducted a study which showed that on achieving goals of keeping heart healthy, one automatically lands on speeding thinking, reducing memory decline and improving thinking skills in course of six years.

The study results were published in the March 16 issue of the Journal of the American Heart Association. It involved more than 1,000 individuals with 72 years as average age. Around two- third were Hispanics, while 19% were Black and 16% were White.

They were given seven goals to achieve by Life’s Simple Seven, a template for heart-healthy living created by the American Heart Association.

On Friday, California Department of Fish and Wildlife (CDFW) officials declared that the Dungeness crabs caught off the coast of California south of the Mendocino-Sonoma County line are safe for eating.

The tests conducted on the crabs in the area, recently, showed that domoic acid levels in them don’t pose a risk to human health anymore. The results of the tests encouraged state officials to raise a closure of the recreational Dungeness crab fishery.

According to the CDFW, besides this, a closure of the commercial Dungeness crab fishery in the region will also be lifted on March 26.

In the north of the Mendocino-Sonoma County line, the closure for the Dungeness crab commercial and recreational fisheries is still effective.

In Flint area, health officials have detected 10th fatal case of Legionnaires’ disease in the middle of an outbreak that, as per many health experts, is linked to the city’s water crisis.
