Webb telescope makes a surprising galactic discovery in the distant universe

Posted by in categories: physics, space

“These objects are way more massive than anyone expected,” said study coauthor Joel Leja, assistant professor of astronomy and astrophysics at Penn State University, in a statement. “We expected only to find tiny, young, baby galaxies at this point in time, but we’ve discovered galaxies as mature as our own in what was previously understood to be the dawn of the universe.”

The telescope observes the universe in infrared light, which is invisible to the human eye, and is capable of detecting the faint light from ancient stars and galaxies. By peering into the distant universe, the observatory can essentially see back in time up to about 13.5 billion years ago. (Scientists have determined the universe is about 13.7 billion years old.)

The operations center for the telescope is in Baltimore City, at the Space Telescope Science Institute on the Johns Hopkins campus.

Russia launches rescue ship to space station after leaks

Posted by in categories: habitats, space

Russia launched a rescue ship on Friday for two cosmonauts and a NASA astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station.

The new, empty Soyuz capsule should arrive at the orbiting lab on Sunday.

World witnesses Moon, Jupiter and Venus in perfect trifecta across skies

Posted by in category: space

The Moon, Jupiter and Venus appeared in a perfect trifecta in skies across the countries in what can be called a rare celestial synchronised dance. Jupiter and Venus and the moon created a triangle-like shape in the sky during nighttime as the celestial bodies came closer to each other.

The mysterious twin of Earth, Venus, and the solar system’s biggest planet, Jupiter, has been getting closer to each other as they move for conjunction on March 1. The planets, Jupiter and Venus, were joined by the moon early in the evening on Wednesday.

NASA aims to send a lander that can survive Venus’ crushing atmosphere

Posted by in category: space

Firstly, the space agency must develop a battery that can withstand Venus’ hellish conditions.

You may be surprised to learn that humans have sent several landers to Venus’ surface. The Soviet Venera missions, for example, transmitted the first-ever image from another planet on October 20, 1975, after sending its Venera 9 lander to the surface of Venus.

That mission lasted less than two hours on the planet’s surface due to the immense atmospheric pressure and scorching temperatures on Earth’s so-called evil twin.

Scientists make a rare find: A Solar system with three Super-Earths

Posted by in categories: physics, space

Three Super-Earths and two Super-Mercuries, a type of planet that is extraordinarily rare and distinct, haʋe Ƅeen found in a star systeм Ƅy astronoмers. Super-Mercuries are so uncoммon—only eight haʋe Ƅeen found so far—that they are extreмely rare.

ESPRESSO’s spectrograph detected two ‘super-Mercury’ worlds in the star systeм HD 23472. Astronoмers haʋe discoʋered that these planets are extreмely rare. This study, puƄlished in Astronoмy &aмp; Astrophysics, looked at how the coмposition of tiny planets ʋaries with planet position, teмperature, and star attriƄutes.

The reason for oƄserʋing this planetary systeм, according to Susana Barros, a researcher at the Institute of Astrophysics e Ciências do Espaço (IA) who led the project, is to characterise the coмposition of sмall planets and to study the transition Ƅetween haʋing an atмosphere and not haʋing an atмosphere.
