Star formation

NASA’s Hubble and Spitzer telescopes have been used to examine a distant elliptical galaxy known as Sparky. The observations represent the first glimpse at the earliest stages of massive galaxy construction, shedding light on an area of frenzied star production in the early universe.  Read More

The Hubble Space Telescope has taken a long-exposure picture of space in the ultraviolet, ...

A newly-released picture taken by the Hubble Telescope is adding more color to the Hubble Ultra Deep Field (HUDF) image by detecting thousands of galaxies in the ultraviolet spectrum. The study, called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF), directly imaged stars and other celestial bodies that would have been impossible to observe on the ground, and gives astronomers critical information that will prove useful as the launch of the more powerful James Webb Space Telescope approaches.  Read More

Magnetars are extremely dense and highly magnetic neutron stars that can form when a star goes supernova. They are extremely rare, and until now, it has been difficult to determine how and why they form. However, thanks to new data collected by the Very Large Telescope (VLT) at the ESO’s Paranal Observatory in Chile, astronomers believe they have finally solved the great mystery.  Read More

Illustris simulation still frame centered on the most massive galaxy cluster existing toda...

As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.  Read More

The ALMA observations give astronomers their best ever look at the formation of a 'monster...

Astronomers have used the Atacama Large Milimeter/submilimeter array (ALMA) in Chile to view the largest stellar womb ever observed in the Milky Way. The gigantic object, which resides within the Spitzer Dark Cloud (SDC), is some 500 times the size of the Sun, and is still experiencing growth.  Read More

SOFIA's FORCAST telescope was used to collect infrared readings from protostar G35.20-0.74

Observations made by NASA's airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have led to a development in our understanding of the formation of massive stars. By studying the star G35, the team found that the formation process was more akin to that of smaller stars than was previously thought.  Read More

Astronomers have used the Herschel space observatory to detect a group of fledgling stars ...

Observations made by the Herschel space observatory have revealed 15 protostars in the constellation Orion, the biggest star formation area near our own solar system. The observatory was the first telescope to reveal the grouping, with previous studies of the area missing the stars which are thought to be some of the youngest and coldest in the constellation. The discovery is a significant step in furthering our understanding of how stars form.  Read More

Artist's conception of a protostar pulling interstellar gas onto a rotating protoplanetary...

The Sun is a bit over 4.5 billion years old, leading many to think of all stars as billions of years in age. Astronomers have now demonstrated that isn't always the case. Using high-resolution millimeter and submillimeter imaging telescope arrays, John Tobin of the National Radio Astronomy Observatory (NRAO) and his collaborators have now discovered an infant star whose age is measured in thousands, rather than billions, of years. While at present the protostar has only about a fifth of the Sun's mass, projections point to the eventual formation of a stellar system broadly similar to our Sun and its planets.  Read More
