Stars going out in style

The colorful, intricate shapes in these NASA Hubble Space Telescope images reveal how the glowing gas ejected by dying Sun-like stars evolves dramatically over time.These gaseous clouds, called planetary nebulae, are created when stars in [...]

New stars found in galaxy

Edwin Hubble once called IC 10 "one of the most curious objects in the sky," and new observations of the extremely faint, lightweight dwarf galaxy are giving scientists new clues about how populations of stars are born.Though th [...]

Neutron stars warp space-time

Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properti [...]

Hot Stars in the Rosette Nebula

Winds and radiation from massive hot stars in the Rosette Nebula have cleared the natal gas and dust from the center of the nearby star-forming region. They also pose a danger to planet forming disks around young, cooler stars in the ne [...]

Light from the first stars

What were the first stars like? No one is yet sure. Our Sun is not a first-generation star. It is not even second generation. The first stars to appear in the universe likely came and went about 13 billion years ago. However, deep obser [...]

why stars twinkle

This is what a star really looks like from the surface of the Earth. To the best the human eye can see, stars are so far away they appear the same as would infinitesimal points of light. The Earth's atmosphere, however, is clumpy, so that [...]

Dying Sun-like Stars Leave Whirlpools

Astronomers based at Jodrell Bank Observatory have found evidence that giant whirlpools form in the wake of stars as they move through clouds in interstellar space. Dr Wareing and his colleagues used the COBRA supercomputer to simulate in [...]

'Van Gogh' Simulations Give New Insight Into Turbulent Stars

Stunning simulations that give a multi-dimensional glimpse into the interior of stars show that material bubbling around the convection zone induces a rich spectrum of internal gravity waves in the stable layers above and below. The swirl [...]

Shields For The Starship Enterprise, A Reality

In the last year space agencies in the United States, Europe, China, Japan and India have announced their intention to resume human exploration of the Solar system, beginning with the Moon and perhaps ultimately moving on to Mars. But trave [...]

Neutron Stars

Neutron stars are created in the final phase of the death of a star that is much more massive than our Sun, but not quite massive enough to become a black hole. After the star explodes in a supernova, what remains is a very small, but incre [...]

Binary Stars

Binary stars are very common in our night sky, but you can't see them using just your eyes. Scientists believe that many, or even most, stars live together as couples in binary systems, bound together by gravity and orbiting each other in a [...]

Stars

We have all gone outside, glanced up at the sky and seen the many points of light that spread across our view like a giant dark carpet sprinkled with glitter. Most of the time, especially if you live in a city like most people do, these lig [...]
