Astronomers accidentally discover massive galaxy in early universe

Astronomers accidentally discover massive galaxy in early universe

Science
Oct. 22 (UPI) -- Astronomers have located evidence of a massive galaxy in the early universe, quelling doubts about the existence of such monstrous galaxies. The discovery was made on accident, they say. While analyzing observations of the distant universe captured by the Atacama Large Millimeter Array, or ALMA, a collection of 66 telescopes in Chile's high desert, scientists spotted a faint blob. Like a ghost, the unexpected glow appeared unconnected to any major cosmic structure. "It was very mysterious because the light seemed not to be linked to any known galaxy at all," lead researcher Christina Williams, an astronomer at the University of Arizona, said in a news release. "When I saw this galaxy was invisible at any other wavelength, I got really excited because it meant that it was...

Astronomers spot oldest galactic protocluster, a giant of the early universe

Science
Sept. 27 (UPI) -- With the help of several powerful telescopes, an international team of astronomers has identified the earliest known protocluster. The protocluster, a constellation of 12 galaxies linked by gravity, formed some 13 billion years ago, when the universe was just 800 million years old. Scientists have described their discovery in a new paper, set to be published in the Astrophysical Journal on September 30. In the present universe, galactic clusters can grow to contain thousands of galaxies. Smaller galaxy clusters can organize to form superclusters, the largest structures in the cosmos. Models suggest there are 10 million superclusters in the observable universe. The protocluster candidate, z66OD, contains a protogalaxy called Himiko, a giant gas cloud and one of the larg...

Spider-Man fans are rejoicing after Sony Pictures and Marvel announced a third Spider-Man film with Tom Holland, allaying fears that the two companies had parted company.In August, Sony said it was "disappointed" not to be working with Disney on future Spider-Man films amid reports that they could not reach a fresh deal over the web-slinging superhero.They hammered out a deal on 26 September, according to Variety.Marvel Studios president Kevin Feige said: "I am thrilled that Spidey's journey in the MCU will continue, and I and all of us at Marvel Studios are very excited that we get to keep working on it."Feige played a big creative role in the last two Spider-Man films, and successfully integrated Holland's character into its multi-billion dollar Marvel ...

Euclid space telescope to study ‘dark Universe’ makes progress

Science
Europe's space mission to uncover the secrets of the "dark Universe" has reached a key milestone.The test model of the Euclid telescope has just emerged from a chamber where it was subjected to the kind of conditions experienced in orbit.It was a critical moment for engineers because the successful trial confirms the observatory's design is on track.Euclid, due for launch in 2022, will map the cosmos for clues to the nature of dark matter and dark energy.These phenomena appear to control the shape and expansion of the Universe but virtually nothing is known about them.The €800m venture, led by the European Space Agency (Esa), will be one of a group of new experiments to come online in the next f
Study explains how supermassive black holes first appeared in the early universe

Study explains how supermassive black holes first appeared in the early universe

Science
June 28 (UPI) -- Scientists have developed a new model for the formation and growth of supermassive black holes that could explain their appearance in the early universe. According to the new study, published this week in the Astrophysical Journal Letters, supermassive black holes grow extremely fast over a very short amount of time, and then very suddenly, stop growing. Scientists came up with the new model to better explain the distribution of supermassive black hole masses and luminosities throughout the distant universe. "This is indirect observational evidence that black holes originate from direct-collapses and not from stellar remnants," Shantanu Basu, an astronomy professor at the University of Western Ontario, said in a news release. Basu and his colleague Arpan Das analyzed th...
