The space - warping quirks of relativity that lead to deviations from Newton's earlier theory of gravity only become obvious on very large scales, but our passive observations of distant planets, stars and galaxies have yet to deliver anything...

Some research has been done to deduce the chemical makeup of very early galaxies, based on observations of very bright, distant galaxies, or of very old stars that formed in the early universe and are still around today, Hewitt said.

Discovering a planet requires confirmation observations to distinguish a true planet orbiting the target star from a distant star that happens to sneak into GPI's field of view — a process that could take years with previous instruments.

These observations have the power of penetrating through interstellar dust and so to unveil the star formation processes in the very distant, dusty galaxies, that constituted the progenitors of local ellipticals.

Ultimately, Priest hopes IRIS observations will bolster studies of more distant stars as well.

They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in these maps as no weak - lensing signal can be measured in these areas.

In the 1990s, observations of exploding stars showed that more distant explosions were dimmer than existing theories predicted.

These first observations indicated an object was very distant and glowing brightly in infrared light, meaning that it was extremely dusty and likely going through a burst of star formation.

The results of follow - up observations (see Table 2) are a mixture of results from photometric follow - up (Deeg et al. 2009), which identifies contaminating» diluted EB's that are more than about 2 distant from the third star - which usually coincides with the observing target -, and from spectroscopic (radial velocity) results, which can only identify signals from sources that fall into the spectrograph's entry slit; that is, they have to be very close (less than 1 - 2) to the target.

u «Three years ago, observations of distant, exploding stars blew to smithereens some of astronomers» most cherished ideas about the universe [the big bang theory].

The famous telescope was named after U.S. astronomer Edwin Hubble, whose observations of variable stars in distant galaxies confirmed that the universe was expanding and gave support to the Big Bang theory.

Unfortunately, however, no single SFR estimator is universally available or even applicable in all circumstances: the numerous galaxies found in deep surveys are often too faint (or too distant) to yield significant detections with most standard SFR measures, and until now there have been no global, multi-band observations of nearby galaxies that span all the conditions under which star - formation is taking place.

Although previous observations with ALMA have found supporting evidence around a low - mass protostar, there was little compelling evidence around massive protostars because most of the massive - star forming regions are rather distant and difficult to investigate in detail.
