James Webb Telescope Reveals Ancient Galaxies In Early Universe Just Looked Like Milky Way

Published

on


The James Webb Space Telescope, which is the most powerful telescope has demonstrated its worthiness for this title by discovering something remarkable. It has spotted galaxies in the early universe that surprisingly resemble our own Milky Way.

Astronomers once thought that young galaxies which started coming together shortly after the Big Bang 13.7 billion years ago, couldn’t have clear shapes like spirals or rings.

They believed these shapes only formed at least six billion years later. But a recent study hints that these detailed shapes might have emerged as early as 3.7 billion years after the Big Bang which is close to the universe’s birth

According to our findings astronomers need to change the way they think about how the first galaxies formed and how galaxies have changed over the last 10 billion years. Christopher Conselice, an astronomy professor at The University of Manchester in the U.K., and one of the authors of the study said in a statement.

Now, when we examine data from the Hubble telescope it initially suggested that early galaxies had uneven shapes due to galactic mergers which was expected. However with the higher-quality data from the JWST, we’re now looking deeper into the universe and discovering that these early galaxies actually had clear and well-defined structures much like our own Milky Way.

This new study emerged shortly after another group of scientists shared their findings using data from the James Webb Space Telescope (JWST). These earlier findings revealed that early galaxies created fewer heavy elements than we thought.

Another Intense Solar Flare Spotted By NASA’s Observatory, Footage Released

Published

As the Sun moves toward solar maximum, it blasted another intense solar flare out into space. According to NASA, the event occurred at 4:38 pm IST on June 11. The agency has shared a footage of the solar blast which was captured by the Solar Dynamics Observatory (SDO) in the low-Earth orbit.

“This flare is classified as an X1.5 flare. X-class denotes the most intense flares, while the number provides more information about its strength,” NASA said about the latest event. Classes A, B, C and M are others which represent the intensity of the flares.

Solar flares are powerful bursts of energy that are released from the Sun occasionally. They are capable of impacting radio communications, power grids and even pose risks to astronauts aboard the International Space Station (ISS).

The month of May was the most active the Sun has been lately as it is reaching the middle of its 11-year-old cycle. This phase is called the solar maximum when the Sun is most violent and the chances of solar flares and subsequent geomagnetic storms are the highest.

On June 10, the National Oceanic and Atmospheric Administration (NOAA) also issued a warning for a coronal mass ejection – the ejection of charged particles toward Earth. When these particles collide with the Earth’s magnetic field, we get auroras.

A Star That Exploded 40 Years Ago Is Breaking The Rules, Scientists Call It A Treasure

Published

on

By


Astronomers are studying a white dwarf star and it is behaving strangely. It is part of a nova system HM Sagittae (HM Sge) that includes the white dwarf and its red giant companion.

A nova event is defined as a brief explosion which causes a blinding flash and sends the accumulating material into outer space.

Using data from the Hubble telescope and the retired SOFIA observatory, scientists have found some baffling characteristics of this binary star system.

Since its explosion about 40 years ago, HM Sge, which lies 3,400 light-years away in the constellation Sagitta, has grown 250 times brighter. Besides, it did not rapidly fade away as novae commonly do, but has maintained its luminosity for decades.

What’s more confusing is that although the system got hotter, it has paradoxically faded a little.

Since HM Sge is a symbiotic star, the dust from the red star and gas of the white dwarf combine to form a blazing hot disk around the latter. This then results in a spontaneous thermonuclear explosion.

Another thing scientists noted was the system’s increase in temperature. According to Hubble’s ultraviolet data, the white dwarf and accretion disk increased from less than 4,00,000 degrees Fahrenheit in 1989 to greater than 450,000 degrees Fahrenheit today.

“When I first saw the new data, I went – ‘wow this is what Hubble UV spectroscopy can do!’ – I mean it’s spectacular, really spectacular,” said Ravi Sankrit, astronomer at the Space Telescope Science Institute (STScI).

Steven Goldman of STScI, who also worked on the study, said that symbiotic stars in our galaxy are rare. “This unique event is a treasure for astrophysicists spanning decades,” he said. The above findings are expected to provide more insights into the physics and dynamics of stellar evolution in binary systems.

Aliens Could Be Living On Earth Disguised As Humans: Harvard Research

Published

on

By



A team of researchers from Harvard University has put forth the possibility of aliens, or “cryptoterrestrials,” covertly living among humans on Earth.

In their paper, which delves into the realm of “unidentified anomalous phenomena” (UAP), commonly known as UFOs and extraterrestrial beings, has sparked a wave of intrigue and speculation within the scientific community.

The study suggests that aliens could be residing underground, on the Moon, or even walking among us, disguised as ordinary humans. It further says that unidentified flying objects (UFOs) or unidentified aerial phenomena (UAP) could be advanced spaceships visiting Earth-based alien friends or allies.

In their research, the experts have introduced the concept of “cryptoterrestrials” – beings that may have originated from Earth’s future, descended from intelligent dinosaurs, or even be remnants of an ancient, technologically advanced human civilization that largely perished long ago.

Admitting that their theories will be regarded skeptically by most scientists, the researchers urged the scientific community to consider their claim “in a spirit of epistemic humility and openness.” Notably, the paper has not been peer-reviewed.

Aliens could be around us in four forms: Scientists

According to the researchers, cryptoterrestrials can come in four forms. The first is human cryptoterrestrials that are technologically advanced ancient human civilisation that continue to exist in remnant form after being destroyed long ago.

Second is Hominid or Theropod Cryptoterrestrials i.e. a technologically advanced non-human civilization consisting of some terrestrial animal which evolved a stealthy way to exist.

Third is former Extraterrestrial or Extratempestrial Cryptoterrestrials – beings that arrived on Earth from elsewhere in the cosmos or from the future and concealed themselves, maybe on the Moon.

And fourth, the scientists said, are entities that are less like homegrown aliens and more like “earthbound angels.”
