It reveals an expansive web of dense (light) and empty (dark) regions. This image is one out of five patches of the sky observed by KiDS. Here the invisible dark matter is seen rendered in pink, covering an area of sky around 420 times the size of the full moon. This image reconstruction was made by analysing the light collected from over three million distant galaxies more than 6 billion light-years away. The observed galaxy images were warped by the gravitational pull of dark matter as the light travelled through the Universe. Some small dark regions, with sharp boundaries, appear in this image. 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.","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/12\/eso1642a1.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":12715,"url":"https:\/\/hobbyspace.com\/Blog\/?p=12715","url_meta":{"origin":1466,"position":3},"title":"New Hubble measurements show universe expanding faster than expected","author":"TopSpacer","date":"June 2, 2016","format":false,"excerpt":"A new finding from the\u00a0NASA\/ESA Hubble Space Telescope Hubble finds Universe may be expanding faster than expected Astronomers have used Hubble to measure the distances to stars in nineteen galaxies more accurately than previously possible.

These are pulsating stars which fade and brighten at rates that are proportional to their true brightness and this property allows astronomers to determine their distances. The researchers calibrated the distances to the Cepheids using a basic geometrical technique called parallax. With Hubble\u2019s sharp-eyed Wide Field Camera 3 (WFC3), they extended the parallax measurements further than previously possible, across the Milky Way galaxy. To get accurate distances to nearby galaxies, the team then looked for galaxies containing both Cepheids and Type Ia supernovae. Type Ia supernovae always have the same intrinsic brightness and are also bright enough to be seen at relatively large distances. By comparing the observed brightness of both types of stars in those nearby galaxies, the team could then accurately measure the true brightness of the supernova. Using this calibrated rung on the distance ladder the accurate distance to additional 300 type Ia supernovae in far-flung galaxies was calculated. They compare those distance measurements with how the light from the supernovae is stretched to longer wavelengths by the expansion of space. Finally, they use these two values to calculate how fast the universe expands with time, called the Hubble constant.","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2016\/06\/heic1611a1-1024x666.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":13806,"url":"https:\/\/hobbyspace.com\/Blog\/?p=13806","url_meta":{"origin":1466,"position":4},"title":"Hubble telescope sees faster than expected expansion of the Universe","author":"TopSpacer","date":"January 26, 2017","format":false,"excerpt":"The latest cosmic finding with the\u00a0Hubble Space Telescope: Cosmic lenses support finding on faster than expected expansion of the Universe By using galaxies as giant gravitational lenses, an international group of astronomers using the NASA\/ESA Hubble Space Telescope has made an independent measurement of how fast the Universe is expanding.\u2026","rel":"","context":"In &quot;Astronomy&quot;","block_context":{"text":"Astronomy","link":"https:\/\/hobbyspace.com\/Blog\/?cat=12"},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/hobbyspace.com\/Blog\/wp-content\/uploads\/2017\/01\/heic1702a1.jpg?resize=350%2C200","width":350,"height":200},"classes":[]},{"id":20581,"url":"https:\/\/hobbyspace.com\/Blog\/?p=20581","url_meta":{"origin":1466,"position":5},"title":"ESO: VLT spots gas halos that fed black holes in earliest galaxies","author":"TopSpacer","date":"December 19, 2019","format":false,"excerpt":"A new ESO (European Southern Observatory) report: ESO Observations Reveal Black Holes' Breakfast at the Cosmic Dawn Astronomers using ESO\u2019s Very Large Telescope have observed reservoirs of cool gas around some of the earliest galaxies in the Universe.
