NASA’s Hubble Space Telescope scientists, on 12th of March, have confirmed that Jupiter’s moon Ganymede has an ocean under its icy surface, and it may contain life.

NASA’s findings have resolved a mystery about the largest moon in the solar system following NASA’s now-defunct Galileo spacecraft, which had previously, during the exploration of Jupiter and its moons from 1995 to 2003, provided hints that Ganymede has a subsurface ocean.

Scientists have revealed that just like Earth, Ganymede too has a liquid iron core that generates a magnetic field, though Ganymede’s field is embedded within Jupiter’s magnetic field. This leads to a set up of an interesting dynamic with tell-tale visuals, twin bands of glowing aurora around Ganymede’s northern and southern polar region.

Atlanta police, on Monday, March 10, have fatally shot down a 27-year-old unarmed, black man Anthony Hill.

The killing was quite similar to the shooting death of Kajieme Powell in St. Louis, when police fatally shot a man clearly showing signs of mental incapacities. They shot him when his neighbors reported police that he was naked and was jumping continually from his two-story apartment balcony.

In the case of Anthony, the police chief has asserted that the officer involved in the shooting had received "mental health" training.

But people believe that if Atlanta police were more informed on mental health, illness and how to engage and assist those struggling with mental health difficulties, then Anthony Hill would have been alive.

Pi Day is an annual celebration commemorating the mathematical constant pi. On Saturday, at about 9:27 am, scientists and mathematicians around the world celebrated the one-in-100-year event in a bizarre manner.

Usually, the International Pi Day is celebrated on March 14 at 1:59 am. The first six digits of the date and time denote the number pi, which is 3.14159, in the United States date format. The event occurs once in a century. This year, the event falls on 14 March. While several pi enthusiasts have decided to celebrate the event at the traditional time, many have already celebrated it at 9:27 am. According to them, the time denotes eight digits of the world's most recognizable mathematical symbols (3.1415927).

In a bid to study the explosive give-and-take of the earth and sun's magnetic fields, NASA launched four identical spacecraft on Thursday. It’s a billion dollar mission and began with the flight of the unmanned Atlas rocket – and NASA’s Magnetospheric Multiscale spacecraft - into a clear-night sky. The launch took place on scheduled time.

NASA has planned to put the four spacecraft into an oblong orbit into the magnetosphere. The orbit stretches tens of thousands of miles into the magnetosphere. The spacecraft are being instructed to fly in pyramid formation, between 6 miles and 250 miles apart. This will help NASA researchers to get access to 3-D views of magnetic reconnection on the smallest of scales.

Blue Bell, on Friday announced a recall following death of three people, who had developed a food-borne illness linked to the ice cream products of the company. The recall was the first in the Texas-based company's 108-year history.

The company has said that all the products produced on the machine with the potential listeria problem were identified and were removed from the stores and storage.

In a statement, the US Food and Drug Administration has said that five adults in Kansas have developed listeriosis after eating the products that were produced at the Blue Bell creamery in Brenham, Texas.

Earlier, the National Aeronautics and Space Administration (NASA) had reported a short circuit in the arm of its Curiosity rover, a car-sized robotic rover which has been exploring the Red Planet. The rover halted work on February 27. Since then, the rover team was working to find the source of short circuit in hopes of repairing it and getting the rover back to work. Now, as per mission controllers, they have discovered the source of short circuits.
