Webb Space Telescope: Seeing far. is very!

  • 14 תגובות
These days, the Webb Space Telescope is expected to take the place of the Hubble Telescope after more than 30 years of operation. How far in space and time (!) can the web reach? What does he see that the human eye is unable to perceive? And how could he help us discover the secrets of the creation of the universe?

Today, Saturday, 25.12.21 at 14:20 (Israel time), the James Webb Space Telescope will be launched, the successor to the Hubble Telescope and a new generation of space telescopes, designed to provide answers to the most intriguing questions in astronomy and astrophysics - the formation of the first galaxies, their birth of stars, the study of the properties of planets in distant solar systems and whether they have life.

Among other things, ARP-MADORE2115-273 was photographed, a rare observation of an interaction between a pair of galaxies and ARP-MADORE0002-503 - a large spiral galaxy with unusually extended spiral arms.

The computer of the space telescope 'Hubble' is still disabled - NASA is trying new strategies to solve the problem

NASA is taking additional steps to investigate the malfunction that happened to the computer of the Hubble space telescope that began on June 13 and caused the suspension of scientific observations. At the same time as the investigation, NASA is looking at indirect ways to activate the backup hardware integrated in the satellite. The telescope itself and the rest of the scientific instruments were not damaged, and they were moved to a safe state
The Hubble Space Telescope was deployed on April 25, 1990 from the high-redundancy space shuttle Discovery. Hubble's location outside the distortions of the atmosphere gives it an unfettered view of stars, planets, and galaxies out to a distance of more than 13.4 billion light-years.

NASA is working to solve a problem with the Hubble Space Telescope's computer. The computer stopped working on Sunday, June 13, shortly after 16:00 p.m. (23:00 p.m. Israel time). This is already the second malfunction of the aging telescope this year

Look around - tidal forces have solved the mystery of dark matter in a distant galaxy

  • 15 תגובות
In 2018, a galaxy with a low amount of dark matter was observed. The galaxy defied all existing models but it turns out that the celebration came earlier than expected and two years later it was announced that tidal forces shed the dark matter. Astronomers are breathing a sigh of relief but the scientific community is still confused, what is dark matter?

In our solar system, the ice giants Rahab (Neptune) and Oron (Uranus), their density is very less compared to that of the rocky planets Venus (Venus) and Earth. However, astrophysicists on NASA's TESS mission have now found an extrasolar planet, TOI-849b, that appears to be 40 times more massive than Earth, while having the same density as Earth. The figure depicts the planet UCF-1.01. As TOI-849b, this planet also orbits close to its sun and is a kind of “hot star.” Credit: NASA/JPL-Caltech

This image, taken by Hubble's Advanced Camera for Surveys, shows part of the globular cluster NGC 6752. Behind the bright stars of the cluster, there is a dense collection of faint-looking stars. They belong to a hitherto unknown spheroidal dwarf galaxy. This galaxy, known as Bedin 1, is about 30 million light-years from Earth. Photo: ESA/Hubble, NASA, Bedin et al.

This image provides three different perspectives on the gamma ray burst GRB150101B, which is similar to the event where gravitational waves were measured and simultaneously also in the electromagnetic spectrum and there is a similarity between the two cases. In the center, an image from the Hubble Space Telescope shows the galaxy where the GRB150101B burst occurred. In the top corner, two X-ray images from NASA's Chandra X-ray Observatory show the event as it appeared on January 9, 2015 (left), and as seen about a month later, on February 10, 2015 (right), as the explosion halo fades, point The bright light is the nucleus of the galaxy.Photo: NASA/CXC

NGC 5256 - a pair of galaxies in the final stages of merging. This object was previously imaged by the Hubble Space Telescope and released as part of a collection of 59 colliding galaxies on the Hubble Space Telescope's 18th birthday, April 24, 2008. The new data clearly show the gas and dust swirling around the galaxy and especially its double center more sharply. This image is a composite of data collected by the Advanced Camera for Surveys and the Wide Angle Camera #3. Photo: NASA/Hubble Space Telescope

Astronomers using the Hubble Space Telescope and a trick of nature have confirmed the existence of a planet orbiting two stars in the OGLE-2007-BLG-349 system, located 8,000 light-years away toward the center of our galaxy. The observations are the first in which a three-body system has been discovered using the micro-cleaning technique
