The Hubble Space Telescope of NASA has captured images of goblin-green objects known as ephemeral quasar ghosts.

Quasar is a very luminous and compact region that surrounds a supermassive black hole at the centre of a galaxy. The Hubble observed them within eight different, distant galaxies. These unusual looped structures orbit their host galaxies and glow in a bright and eerie goblin-green hue.

According to scientists, these glowing structures have looping, helical and braided shapes and they don't fit a single pattern.

Quasars are the most active of these galaxy cores, where infalling material is heated to a point where a brilliant searchlight shines into deep space. The beam is produced by a disk of glowing, superheated gas encircling the black hole.

According to the National Aeronautics and Space Administration (NASA), public must watch next test flight of its flying saucer-shaped vehicle. The United States space agency stated that the vehicle is capable of landing heavy payloads on the Red Planet.

While providing information about the vehicle Low Density Supersonic Decelerator (LDSD), the space agency stated that the vehicle is 15 feet wide and its weight is more than three tons. LDSD has a two-part breaking system which contains an inflatable braking shield and a huge parachute.

An Alabama mother delivered a baby without nose nasal passage or sinus cavities in the late afternoon of March.

The child named Eli Thompson weighs 6 pounds and 8 ounces. He is born with a disorder, called complete congenital arhinia. According to the experts, the disorder is so rare that there are only 38 known reported cases of it worldwide.

Baby’s mom Brandi McGlathery told ABC News, "The day I delivered, everything went fine. At 4:42 when he was born, he came out and the doctor put him on my chest. When I took a closer look at him, I said, 'He doesn't have a nose,' and they took him out of the room”.

A research published in the Journal of Sleep Research unveiled that ‘exploding head syndrome’ affects one-fifth of college students.

The syndrome involves hearing sudden, loud noises when affected people go to sleep and wake up. Not much is known about the condition, but one thing has become clear that it not affects older people, but people of other age as well.

Researchers from Washington State University carried out a study on 211 students. They were assessed for having the syndrome and sleep paralysis. Out of them, 18% were reported of having the syndrome at least once.

A new study has revealed that sitting in front or near the TV does not make children nearsighted.

Nearsightedness or myopia typically develops between age eight and 12 years. The problem affects one-third of adults.

According to the study, a new test can accurately predict if a child will become nearsighted. According to the researchers, their current refractive error, or eyeglasses prescription can be used to detect the problem.

According to Karla Zadnik, dean of the College of Optometry at Ohio State University and lead author of the study, children hardly reveal their parents that they can't see the board in class. Also, the letter-chart screening tests used by schools and pediatricians are nor ideal.

The National Alliance on Mental Illness has expressed its sadness over the crash of Germanwings Flight 9525. It gave condolences to the families of those who lost their lives in this senseless tragedy.

It has been said that the co-pilot crashed the plane as he suffered from depression and developed suicidal tendencies. A German prosecutor has most recently reported that the co-pilot had attended sessions of psychotherapy for an extended period of time and suicidal tendencies were noted in him.

The airline has reported that he disclosed to them in 2009 that he had a previous episode of severe depression. He received the treatment for the condition before receiving his pilot’s license.
