Sentences with phrase «nearby star clusters»

The brightest object in a nearby star cluster, thought for decades to be a single star, is actually two massive stars in the process of merging.

Not exact matches

Gas at the centre of galaxy clusters should be cooling as it loses energy; this would allow nearby material to compress the gas and create ideal conditions for making stars.

Globular clusters contain far lower concentrations of the planet - forming heavy elements — such as carbon, oxygen, and iron — than do our sun and nearby stars, leading some to suspect that it might be difficult for planets to form there.

That's also the distance to most stars in the nearby Big Dipper, which makes it likely that they all belong to the same association, or loose star cluster.

This image from the Wide Field Imager (WFI) on the MPG / ESO 2.2 - metre telescope at La Silla, shows the cluster and the gas clouds surrounding it, which glow in orange and red hues due to the radiation coming from nearby hot stars.

Remarkably, the distribution of star - forming galaxies around a cluster of galaxies in the more distant universe (5 billion years ago) corresponds much more closely with the weak lensing map than a slice of the more nearby universe (3 billion years ago).

The lens could lie within or nearby the galaxy, and could be a collection of thousands of stars like a globular cluster.

These rare systems — only a few tens were known until recently — were thought to have had their outer coats of stars ripped away by the gravity of other, larger galaxies as they passed nearby, a theory supported by the fact that they were usually found in the centers of large clusters of galaxies.

Meanwhile, we also will have sent clusters of spacecraft to 15 or so nearby stars.

Last month, at a meeting at the University of Maryland, Ozernoy presented calculations of how Sagittarius A * pulls in material from a nearby cluster of hot blue stars.

The Substellar Objects in Nearby Young Clusters (SONYC) survey included the star cluster NGC 1333, 1000 light years away in the constellation of Perseus.

By comparing this new diagram to the Hertzsprung - Russell diagram for the nearby stars, you will see that the ratio of the observed apparent brightness to the absolute brightness is the same for every kind of star - and this ratio gives you then the distance to the cluster.

Gillian Wilson, professor of physics and astronomy at UC Riverside, added, «Fascinatingly, however, the study found that the percentage of galaxies which had stopped forming stars in those young, distant clusters, was much lower than the percentage found in much older, nearby clusters.

While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time.

A nearby companion galaxy, NGC 5195, off the edge of this image, gravitational pull is triggering star formation in the main galaxy, as seen in brilliant detail by numerous, luminous clusters of young and energetic stars.

Because it is above the atmosphere, the Hubble Space Telescope can detect these small dead stars in nearby old star clusters called globular clusters.

We have also more images of the region of M8 and M20, which sometimes also include the nearby open star cluster M21.

The team also mapped out all the positions of the brightest nearby cluster stars and was able to detect very small motions as the stars slowly revolved around each other.
