Webb Confirms a Longstanding Galaxy Model

02-11-2024 17:05 via universetoday.com

Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies. This is why observatories such as the James Webb Space Telescope (JWST) are so useful. With it, we can study in detail how galaxies formed and evolved. We are now at the point where our observations allow us to confirm long-standing galactic models, as a recent study shows.This par

The Aftermath of a Neutron Star Collision Resembles the Conditions in the Early Universe

02-11-2024 17:04 via universetoday.com

Neutron stars are extraordinarily dense objects, the densest in the Universe. They pack a lot of matter into a small space and can squeeze several solar masses into a radius of 20 km. When two neutron stars collide, they release an enormous amount of energy as a kilonova.
That energy tears atoms apart into a plasma of detached electrons and atomic nuclei, reminiscent of the early Universe after the Big Bang.Even though kilonova are extraordinarily energetic, they’re difficult to obser

New View of Venus Reveals Previously Hidden Impact Craters

02-11-2024 14:01 via universetoday.com

Think of the Moon and most people will imagine a barren world pockmarked with craters. The same is likely true of Mars albeit more red in colour than grey! The Earth too has had its fair share of craters, some of them large but most of the evidence has been eroded by centuries of weathering. Surprisingly perhaps, Venus, the second planet from the Sun does not have the same weathering processes as we have on Earth yet there are signs of impact craters, but no large impact basins!

Onderzoek toont aan dat Uranusmaan Miranda mogelijks een oceaan onder het oppervlak heeft

02-11-2024 11:17 via spacepage.be

Een nieuwe studie suggereert dat Uranusmaan Miranda een wateroceaan onder zijn oppervlak kan hebben, een bevinding die veel aannames over de geschiedenis en samenstelling van de maan in twijfel trekt en hem in het gezelschap kan plaatsen van de weinige werelden in ons zonnestelsel met mogelijk levensonderhoudende omgevingen. “Om bewijs te vinden van een oceaan in een klein object als Miranda is ongelooflijk verrassend,” zei Tom Nordheim, een planeetwetenschapper aan het Johns Hopkins

Onderzoekers ontdekken een van de snelst draaiende sterren in het heelal

02-11-2024 08:37 via spacepage.be

De Melkweg heeft nog steeds veel geheimen over het heelal. Onderzoekers van DTU (Danmarks Tekniske Universitet) zijn er nu in geslaagd om er nog een te ontdekken met behulp van een röntgenruimtetelescoop op het internationale ruimtestation (ISS). Het is een klein maar extreem zwaar en snel draaiend object, een neutronenster, onderdeel van een zogenaamd 'röntgenbinaire stersysteem' met de naam '4U 1820-30'. Het hemelobject bevindt zich in het sterrenbeeld Boogschutter, in de buurt van h

Multimode Propulsion Could Revolutionize How We Launch Things to Space

02-11-2024 03:04 via universetoday.com

In a few years, as part of the Artemis Program, NASA will send the “first woman and first person of color” to the lunar surface. This will be the first time astronauts have set foot on the Moon since the Apollo 17 mission in 1972. This will be followed by the creation of permanent infrastructure that will allow for regular missions to the surface (once a year) and a “sustained program of lunar exploration and development.” This will require spacecraft making regular trips

China Trains Next Batch of Taikonauts

02-11-2024 02:31 via universetoday.com

China has a fabulously rich history when it comes to space travel and was among the first to experiment in rocket technology. The invention of the rocket is often attributed to the Sung Dynasty (AD 960-1279.) Since then, China has been keen to develop and build its own space industry. The Chinese National Space Administration has already successfully landed probes on the Moon but is preparing for their first human landers. Chinese astronauts are sometimes known as taikonauts and CNSA has just co

NASA Focusses in on Artemis III Landing Sites.

02-11-2024 01:14 via universetoday.com

It was 1969 that humans first set foot on the Moon. Back then, the Apollo mission was the focus of the attempts to land on the Moon but now, over 50 years on, it looks like we are set to head back. The Artemis project is the program that hopes to take us back to the Moon again and it’s going from strength to strength. The plan is to get humans back on the Moon by 2025 as part of Artemis III. As a prelude to this, NASA is now turning its attention to the possible landing sites. The Art
