It’s a Planet: New evidence of Baby Planet in the making

Astronomers agree that planets are born in protoplanetary disks – rings of dust and gas that surround young, newborn stars. While hundreds of these disks have been spotted throughout the universe, observations of actual planetary birth and formation have proved difficult within these environments.

Now, astronomers at the Center for Astrophysics | Harvard & Smithsonian have developed a new way to detect these elusive newborn planets — and with it, “smoking gun” evidence of a small Neptune or Saturn-like planet lurking in a disk. The results are described today in The Astrophysical Journal Letters.

“Directly detecting young planets is very challenging and has so far only been successful in one or two cases,” says Feng ...

Mysterious Diamonds came from Outer Space, scientists say

Strange diamonds from an ancient dwarf planet in our solar system may have formed shortly after the dwarf planet collided with a large asteroid about 4.5 billion years ago, according to scientists.

The research team says they have confirmed the existence of lonsdaleite, a rare hexagonal form of diamond, in ureilite meteorites from the mantle of the dwarf planet.

Lonsdaleite is named after the famous British pioneering female crystallographer Dame Kathleen Lonsdale, who was the first woman elected as a Fellow to the Royal Society.

The team—with scientists from Monash University, RM...

Webb Telescope Captures ‘Breathtaking’ Images of Orion Nebula

The wall of dense gas and dust resembles a massive winged creature, its glowing maw lit by a bright star as it soars through cosmic filaments.

An international research team on Monday revealed the first images of the Orion Nebula captured with the James Webb Space Telescope, leaving astronomers “blown away.”

The stellar nursery is situated in the constellation Orion, 1,350 light-years away from Earth, in a similar setting in which our own solar system was birthed more than 4.5 billion years ago.

Astronomers are interested in the region to better understand what happened during the first million years of our planetary evolution.

The images were obtained as part of the Early Release Science program and involved more than 100 scientists in 18 countries, with insti...

Astronomy: Is Overeating to blame for Bulges in Milky Way Bar?

A new simulation conducted on the world’s most powerful supercomputer dedicated to astronomy has produced a testable scenario to explain the appearance of the bar of the Milky Way. Comparing this scenario to data from current and future space telescopes will help clarify the evolution of our home Galaxy.

Astronomy is revealing the structure of the Milky Way Galaxy in which we live in increasing detail. We know that it is a disk galaxy, with two- or four- armed spirals, with a straight bar in the middle connecting the spirals...
