Nasty Star

Hubble Observes Unique Star Dubbed "Nasty"

Astronomers using the Hubble Space Telescope have found surprising new clues about a large, fast aging star that has never been seen before in the Milky Way galaxy. In fact, the star is so different that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. This strange star may represent a brief transitory stage in the evolution of extremely massive stars.

Sun Experiences Seasons Just Like the Earth

A new study has found that just like the Earth, our Sun experiences seasonal changes which scientists believe can now help them better predict solar storms.

With the Help of ALMA Astronomers Find Complex Organic Molecules in Infant Solar System

While researchers have long believed that the circumstances and the molecular structures involved in the creation of our Sun and of our Earth were unique, it appears that far off in space there may be another solar system brimming with potential for life someday. Utilizing the Atacama Large Millimeter/submillimeter Array (ALMA) researchers with the National Radio Astronomy Observatory have detected for the first time ever the complex organic molecules necessary to create life in a protoplanetary disk surrounding an infant star only a million years into its formation.

Astronomers Adopt a Forming Star, Watching it Grow for 18 Years 4200 Light-Years Away

While researchers may have missed the formation of our very own Sun by a few billion years, in essence they have become surrogate parents to many other stars formed since the dawn of the telescope. Watching one such infant star well into its adulthood, researchers with the National Radio Astronomy Observatory this week released a time lapse of one such star, affectionately named “W75N(B)-VLA 2”, which reveals the earliest formations of a massive young star over the course of 18 years. The beginning and ending images released this week reveal a dramatic difference in the star’s developmental stages and highlights theories that astronomers have posited for decades, as they wondered if they would ever catch a glimpse of stars forming in such a way as researchers today have been able to do.

Dust on the Ocean Floor Reveals Ancient Supernova

Scientists have made a startling discovery while exploring the ocean floor that could change how we understand supernovae. Researchers now believe that exploding stars, often far beyond the confines of our solar system, have deposited extraterrestrial dust at the bottom of the oceans, and that could give us better insights into the composition of far off galaxies.

NuSTAR Telescope Helps NASA Find Nanoflares on the Sun

With a new day in science comes a new study of the sun. No, we’re not talking about a new telescope or a new division under the international space agencies, but rather a reallocation of a science used in other parts of space. Turning their sights from far off black holes, with a closer subject in mind, NASA’s Solar Dynamics Observatory (SDO) is repositioning their NuSTAR (Nuclear Spectroscopic Telescope Array) towards our very own local star to produce the most sensitive measurements of high-energy solar x-rays to date.

ALMA Imaging Reveals Emerging Planets in Nearby Taurus Constellation

Well it appears that the cosmic gestational period is over, and astronomers are catching a glimpse at what happens next. This week researchers at the Chilean Atacama Large Millimeter/submillimeter Array (ALMA) observatory have revealed that in the constellation Taurus, that new life is forming—or at least new planets.
Partial Solar Eclipse

Taking A Bite Out of Sunlight—US Expects A Partial Solar Eclipse

Predicted to occur this Thursday, Oct. 23, the off-center new moon will pass in front of the sun creating a partial solar eclipse seen across the United States. Though the predicted visibility will range anywhere from twelve to seventy percent of clarity, researchers at NASA expect that the event will be widely visible across the entire continental US.
