Are there 6 new galaxies?
Webb Telescope Finds Evidence of Massive Galaxies That Defy Theories of the Early Universe. Astronomers have identified what appear to be six massive galaxies from the infancy of the universe. The objects are so massive, that if confirmed, they could change how we think of the origins of galaxies.
NASA's James Webb telescope has found six big galaxies that are changing our understanding of the entire universe. The new observations indicate the presence of mature and large, but compact galaxies swarming with stars way sooner than scientists thought was possible.
NASA's James Webb Space Telescope (JWST) keeps spotting galaxies that are too big to exist, scientists have claimed. Six of these star clusters are far too massive to be the age their data suggests they are, which is between 500 and 700 million years old.
The seven galaxies confirmed by Webb were first established as candidates for observation using data from the Hubble Space Telescope's Frontier Fields program. The program dedicated Hubble time to observations using gravitational lensing, to observe very distant galaxies in detail.
Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new quiescent galaxy. The galaxy, designated JADES-GS+53.15508-27.80178, was found at a high redshift and has a relatively low mass.
Our Milky Way galaxy is destined to collide with our closest large neighbour, the Andromeda galaxy, in about five billion years.
Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us.
In addition to Andromeda Galaxy, James Webb Telescope observed Pulsars, Comets, Protostars and other Galaxies this week.
The James Webb Space Telescope keeps finding galaxies that shouldn't exist, a scientist has warned. Six of the earliest and most massive galaxies that Nasa's breakthrough telescope has seen so far appear to be bigger and more mature than they should be given where they are in the universe, researchers have warned.
Webb can view more energetic phenomena including forming proto-stars and very distant galaxies. Getting data with both telescopes on the same objects can build a more complete picture of the astrophysical processes.
What is the farthest galaxy detected by Webb?
The two most distant galaxies, both detected in JWST images, have redshifts of 13.20 and 12.63, making them the most distant galaxies confirmed by spectroscopy to date. A redshift of 13.2 corresponds to about 13.5 billion years ago.
Webb will observe Mars and the giant planets, minor planets like Pluto and Eris - and even the small bodies in our solar system: asteroids, comets, and Kuiper Belt Objects.
Earendel started shining just 900 million years after the Big Bang, and it is only observable because of an extraordinary cosmic coincidence. The James Webb Space Telescope captured the most distant known star, Earendel, in this deep field shot released Aug.
Compared to other types of galaxies, elliptical galaxies have smaller portions of gas and dust, contain older stars, and don't form many new stars. The largest and rarest of these galaxies – known as giant ellipticals – are about 300,000 light-years across.
How can a star be older than the universe?
The total size of the universe is unknown. Recent research suggests it may be infinite, implying that there could be an infinite number of galaxies. However, there is a limit beyond which we cannot see; because light from beyond has not had time to reach Earth since the Big Bang.
The eventual merger is still at least 2.5 billion years away. So our home planet and the solar system is safe until then. But after that, it is bad news for Earth. Depending on the position of the solar system, Earth can be exposed to more radiation from nearby stars resulting in inhospitable temperatures.
The Andromeda Galaxy (M31) is indeed approaching us, by about 300 kilometers (190 miles) per second measured with respect to the Sun. If you subtract the Sun's orbital motion around our galaxy (about 230 km per second toward Cygnus), M31 is still approaching the Milky Way by about 130 km per second.
Can the Andromeda Galaxy support life? Since we can't yet say for certain whether there are any other stars in our own galaxy that host life, it is even harder to say whether there might be life, or at least the conditions for life, in another galaxy.
Now the Andromeda galaxy can be seen with the naked eye, like a tiny dot in the sky. But in three billion years it will be so clearly visible to the naked eye that it will even be possible to see individual spiral arms in it.
How long would it take to leave the Milky Way?
Even traveling at the speed of light, it would take nearly a hundred thousand years!
Travel Time
To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager's speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!
For the first time, astronomers have found evidence of an ancient mass migration of stars into another galaxy. They spotted over 7,000 stars in Andromeda (M31), our nearest neighbor, that merged into the galaxy about two billion years ago.
Fortunately, NASA astronauts have a slew of tips for avoiding jet lag along the way. "If you want to get to farther out vacation spots," the video explains, "you'll probably need more than a few extra snacks. A trip to the Andromeda Galaxy, our nearest large neighbor galaxy, can take over one million years.
Does the Andromeda Galaxy have planets? There is currently only one very strong candidate planet in the Andromeda Galaxy, temporarily named PA-99-N2. It was detected because of a microlensing event in 1999.
James Webb telescope detects evidence of ancient 'universe breaker' galaxies. The James Webb space telescope has detected what appear to be six massive ancient galaxies, which astronomers are calling “universe breakers” because their existence could upend current theories of cosmology.
The telescope's sensors have detected six different deformations from recent micrometeoroid strikes. The James Webb Space Telescope that just provided the world with the deepest-ever view of the universe has been permanently damaged by asteroid attacks.
“The six galaxies we found are more than 12 billion years old, only 500 to 700 million years after the Big Bang, reaching sizes up to 100 billion times the mass of our sun. This is too big to even exist within current models.
The James Webb Space Telescope set its sights on a galaxy 20 million light-years away, capturing a dazzling star-forming galaxy in images streaked with the signature of passing asteroids.
Using its infrared-sensing instruments, the telescope can peer past dusty regions of space to study light that was emitted more than 13 billion years ago by the most ancient stars and galaxies in the universe.
Are we looking into the past in space?
The time it takes for light from objects in space to reach Earth means that when we look at planets, stars and galaxies, we're actually peering back in time.
GN-z11 is a high-redshift galaxy found in the constellation Ursa Major. It is among the farthest known galaxies from Earth ever discovered. The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
The most distant planet in the Solar System is Neptune, which orbits the Sun at an average distance of 4.498 billion km (2.794 billion miles). Neptune was discovered by the German astronomer Johann Gottfried Galle on 23 September 1846.
System dates back to just 600 million years after the big bang. Astronomers have measured the distance to the farthest cosmic object known to humankind: a galaxy that lies 13.1 billion light-years away.
Webb will be able to observe galaxies that formed about 400 million years after the big bang.
Scientists designed the James Webb Space Telescope to be able to detect faint light from distant parts of the universe. But with a few careful adjustments, the high-tech telescope was recently able to turn its attention toward a much closer and brighter object in the night sky: Mars.
Webb discovers brown dwarf with sand clouds
Though many telescopes have identified exoplanets, Webb wasn't designed to. But discover one it did — and it's an exceptionally weird one. For one, VHS 1256 b isn't a planet at all. It's a brown dwarf — bigger than a planet, but too small to be a proper star.
Hubble's Impact
Among its famous observations is the Hubble Ultra Deep field, the deepest image of the universe ever made at visible and near-infrared wavelengths, and revealed over 10,000 galaxies in a small patch of sky.
One such estimate says that there are between 100 and 200 billion galaxies in the observable universe.
Webb Space Telescope Detects Universe's Most Distant Complex Organic Molecules. June 5, 2023 — Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist.
What are the new findings of James Webb?
The James Webb Space Telescope discovers enormous distant galaxies that should not exist. Giant, mature galaxies seem to have filled the universe shortly after the Big Bang, and astronomers are puzzled. Nobody expected them. They were not supposed to be there.
