1st image: A representation of the evolution of the universe over 13.77 billion years. The far left depicts the earliest moment we can now probe, when a period of “inflation” produced a burst of exponential growth in the universe. (Size is depicted by the vertical extent of the grid in this graphic.) For the next several billion years, the expansion of the universe gradually slowed down as the matter in the universe pulled on itself via gravity. More recently, the expansion has begun to speed up again as the repulsive effects of dark energy have come to dominate the expansion of the universe. Credit: NASA’s Goddard Space Flight Center

2nd image: This collection of 36 images from NASA’s Hubble Space Telescope features galaxies that are all hosts to both Cepheid variables and supernovae. These two celestial phenomena are both crucial tools used by astronomers to determine astronomical distance, and have been used to refine our measurement of the Hubble constant, the expansion rate of the universe. The galaxies shown in this photo (from top row, left to bottom row, right) are: NGC 7541, NGC 3021, NGC 5643, NGC 3254, NGC 3147, NGC 105, NGC 2608, NGC 3583, NGC 3147, Mrk 1337, NGC 5861, NGC 2525, NGC 1015, UGC 9391, NGC 691, NGC 7678, NGC 2442, NGC 5468, NGC 5917, NGC 4639, NGC 3972, The Antennae Galaxies, NGC 5584, M106, NGC 7250, NGC 3370, NGC 5728, NGC 4424, NGC 1559, NGC 3982, NGC 1448, NGC 4680, M101, NGC 1365, NGC 7329, and NGC 3447.

Mystery of Universe’s Expansion Rate: Hubble Data Shows That “Something Weird” Is Going On

Science history will record that the search for the expansion rate of the universe was the great Holy Grail of 20th-century cosmology. Without any observational evidence for space expanding, contracting, or standing still, we wouldn’t have a clue as to whether the universe was coming or going. Furthermore, we wouldn’t have any idea about its age either – or in fact, if the universe was eternal.

The first act of this revelation came when, a century ago, American astronomer Edwin Hubble discovered myriad galaxies outside of our home galaxy, the Milky Way. And, the galaxies weren’t standing still. Hubble found that the farther a galaxy is, the faster it appears to be moving away from us. This could be interpreted as the uniform expansion of space. Hubble even said that he studied the galaxies simply as “markers of space.” However, he was never fully convinced of the idea of a uniformly expanding universe. He suspected his measurements might be evidence of something else more oddball going on in the universe.  ...

From SpaceTelescope.Org Picture of the Week; April 24, 2017:

A Matter of Distance

In space, being outshone is an occupational hazard. This NASA/ESA Hubble Space Telescope image captures a galaxy named NGC 7250. Despite being remarkable in its own right — it has bright bursts of star formation and recorded supernova explosions — it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it.

This bright object is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard), much closer than the much more distant galaxy. Only this way a normal star can outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

In this case TYC 3203-450-1 million times closer than NGC 7250 which lies over 45 million light-years away from us. Would the star be the same distance as NGC 7250, it would hardly be visible in this image.

[andromeda1023]

NGC 7250, also known as LEDA 68535, Mrk 907, and UGC 11980, is a 13th-magnitude irregular galaxy.

It was discovered on November 8, 1790 by the English astronomer William Herschel.

NGC 7250 is located in the constellation Lacerta, approximately 31 million light-years away.

It is about 25,000 light-years across and is characterized by the ‘dual cores’ in its center.

The dual-core feature might be interpreted by the interaction of two galaxies in the past.

NGC 7250 is also a starburst galaxy, meaning it is currently undergoing a period of exceptionally high rates of star formation.

In 2013, a Type Ia supernova — now called SN 2013dy — was discovered in NGC 7250 by the Lick Observatory Supernova Search and Japanese astronomer Kuniaki Goto.

Despite being remarkable in its own right, NGC 7250 blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it.

This bright object is a single and little-studied star named TYC 3203-450-1.

Astronomers studying distant objects call these stars ‘foreground stars’ and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

This image of NGC 7250 is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3).

It is based on data obtained through four WFC3 filters.

The color results from assigning different hues to each monochromatic image associated with an individual filter.

[netmassimo]

An image captured by the Hubble Space Telescope portrays the irregular galaxy NGC 7250, along with the star TYC 3203-450-1, which is much closer and thus from the Earth looks much brighter than a whole galaxy. That star's presence makes studying the galaxy more difficult because its light interferes with NGC 7250's dimmer light, polluting the observations of an object that's interesting because of its peculiar characteristics.
