(TMU) — Using the combined power of multiple astronomical observatories across the world, astronomers have discovered a stunning set of 39 massive galaxies that had previously been invisible.
The multiple discovery is the first of its kind, according to a study published on Wednesday in Nature, and is set to forever change the way in which scientists look at how galaxies are formed.
The galaxies, which are located billions of light-years away, are intimately connected with supermassive black holes and the distribution of dark matter.
In a press release, lead researcher Tao Wang at the University of Tokyo said:
“This is the first time that such a large population of massive galaxies was confirmed during the first 2 billion years of the 13.7-billion-year life of the universe. These were previously invisible to us … This finding contravenes current models for that period of cosmic evolution and will help to add some details, which have been missing until now.”
And while the Hubble Space Telescope has allowed astronomers to gain major insights into previously unknown parts of the universe, the research team from the University of Tokyo relied on the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile to uncover this latest massive find.
And it appears that the huge galaxies would overwhelm our humble view of the heavens if they were actually visible to us humans. Given the age and distance of the huge galaxies, they have always been hidden from our view thanks to the weak and stretched light emanating from them. As a result of such distance, the visible light becomes infrared.
Kotaro Kohno, the study’s author and a professor at the University of Tokyo, explained:
“The light from these galaxies is very faint with long wavelengths invisible to our eyes and undetectable by Hubble.
So we turned to the Atacama Large Millimeter/submillimeter Array (ALMA), which is ideal for viewing these kinds of things. I have a long history with that facility and so knew it would deliver good results.”
The infrared light from the distant galaxies was originally revealed by the NASA Spitzer Space Telescope before ALMA’s “sharp eyes” detected them, cutting through the thick dust that obscured them from our sight, Wang explained.
“It took further data from the imaginatively named Very Large Telescope in Chile to really prove we were seeing ancient massive galaxies where none had been seen before.”
The new discovery will also shed light on the existence of supermassive black holes. Professor Kohno explained:
“The more massive a galaxy, the more massive the supermassive black hole at its heart. So the study of these galaxies and their evolution will tell us more about the evolution of supermassive black holes, too.
Massive galaxies are also intimately connected with the distribution of invisible dark matter. This plays a role in shaping the structure and distribution of galaxies. Theoretical researchers will need to update their theories now.”
So what would the sky look like if we happened to live in one of these ancient, massive galaxies? Wang explained:
“For one thing, the night sky would appear far more majestic. The greater density of stars means there would be many more stars close by appearing larger and brighter … But conversely, the large amount of dust means farther-away stars would be far less visible, so the background to these bright close stars might be a vast dark void.”
Wang is sure that in the future, new space-based telescopic technology will be able to reveal the chemicals, number of stars and basic composition of the dozens of galaxies that have been revealed. He explained:
“Previous studies have found extremely active star-forming galaxies in the early Universe, but their population is quite limited.
Star formation in the dark galaxies we identified is less intense, but they are 100 times more abundant than the extreme starbursts. It is important to study such a major component of the history of the Universe to comprehend galaxy formation.”
Dolphin Swims Through Louisiana Neighborhood in Aftermath of Hurricane Ida
A Louisiana family was shocked to find a dolphin swimming through their neighborhood in the aftermath of Hurricane Ida.
Amanda Huling and her family were assessing the damage to their neighborhood in Slidell, Louisiana, when they noticed the dolphin swimming through the inundated suburban landscape.
In video shot by Huling, the marine mammal’s dorsal fin can be seen emerging from the water.
“The dolphin was still there as of last night but I am in contact with an organization who is going to be rescuing it within the next few days if it is still there,” Huling told FOX 35.
Ida slammed into the coast of Louisiana this past weekend. The Category 4 hurricane ravaged the power grid of the region, plunging residents of New Orleans and upwards of 1 million homes and businesses in Louisiana and Mississippi into the dark for an indefinite period of time.
Officials have warned that the damage has been so extensive that it could take weeks to repair the power grid, reports Associated Press.
Also in Slidell, a 71-year-old man was attacked by an alligator over the weekend while he was in his flooded shed. The man went missing and is assumed dead, reports WDSU.
Internet users began growing weary last year about the steady stream of stories belonging to a “nature is healing” genre, as people stayed indoors and stories emerged about animals taking back their environs be it in the sea or in our suburbs.
However, these latest events are the surreal realities of a world in which extreme weather events are fast becoming the new normal – disrupting our lives in sometimes predictable, and occasionally shocking and surreal, ways.
Mom in LA Suburbs Fights Off Mountain Lion With Bare Hands, Rescues 5-Year-Old Son
A mother in Southern California is being hailed as a hero after rescuing her five-year-old son from an attacking mountain lion.
The little boy was playing outside his home in Calabasas, a city lying west of Los Angeles in the Santa Monica Mountains, when the large cat pounced on him.
The 65-pound (30 kg) mountain lion dragged the boy about 45 yards across the front lawn before the mother acted fast, running out and striking the creature with her bare hands and forcing it to free her son.
“The true hero of this story is his mom because she absolutely saved her son’s life,” California Department of Fish and Wildlife spokesman Captain Patrick Foy told Associated Press on Saturday.
“She ran out of the house and started punching and striking the mountain lion with her bare hands and got him off her son,” Foy added.
The boy sustained significant injuries to his head, neck and upper torso, but is now in stable condition at a hospital in Los Angeles, according to authorities.
The mountain lion was later located and killed by an officer with the California Department of Fish and Wildlife, who found the big cat crouching in the bushes with its “ears back and hissing” at the officer shortly after he arrived at the property.
“Due to its behavior and proximity to the attack, the warden believed it was likely the attacking lion and to protect public safety shot and killed it on sight,” the wildlife department noted in its statement.
The mountain lion attack is the first such attack on a human in Los Angeles County since 1995, according to Fish and Wildlife.
The Santa Monica Mountains is a biodiverse region teeming with wildlife such as large raptors, mountain lions, bears, coyote, deer, lizards, and snakes. However, their numbers have rapidly faded in recent years, causing local wildlife authorities to find new ways to manage the region’s endemic species.
Video Shows Taliban Taking Joyride in Captured US Blackhawk Helicopter
The rapid fall of Kabul to the Taliban has resulted in a number of surreal sights – from footage of the Islamist group’s fighters exercising at a presidential gym to clips of combatants having a great time on bumper cars at the local fun park.
However, a new video of Taliban members seemingly testing their skills in the cockpit of a commandeered UH-60 Black Hawk helicopter shows the chilling extent to which U.S. wares have fallen into the hands of a group it spent trillions of dollars, and exhaustive resources, to stamp out.
In the new video, shared on Twitter, the front-line utility helicopter can be seen taxiing on the ground at Kandahar Airport in southeastern Afghanistan, moving along the tarmac. It is unclear who exactly was sitting in the cockpit, and the Black Hawk cannot be seen taking off or flying.
It is unlikely that the Taliban have any combatants who are sufficiently trained to fly a UH-60 Black Hawk.
The helicopter, which carries a $6 million price tag, is just a small part of the massive haul that fell into the militant group’s hands after the country’s central government seemingly evaporated on Aug. 14 amid the withdrawal of U.S. and coalition troops.
Some 200,000 firearms, 20,000 Humvees and hundreds of aircraft financed by Washington for the now-defunct Afghan Army are believed to be in the possession of the Taliban.
The firearms include M24 sniper rifles, M18 assault weapons, anti-tank missiles, automatic grenade launchers, rocket-propelled grenades and mortars.
Taliban fighters in the elite Badri 313 Brigade have been seen in propaganda images showing off in uniforms and wielding weaponry meant for the special forces units of the Afghan Army.
The U.S. is known to have purchased 42,000 light tactical vehicles, 9,000 medium tactical vehicles and over 22,000 Humvees between 2003 and 2016.
The White House remains unclear on how much weaponry has fallen into Taliban hands, with National Security Adviser Jake Sullivan admitting last week that the U.S. lacks a “clear picture of just how much missing $83 billion of military inventory” the group has.
