There are some things that never cease to amaze me and the discovery of distant objects is one of them. The James Webb Space Telescope has just found the most distant galaxy ever observed! It has the catchy title JADES-GS-z14-0 and it has a redshift of 14.32. This means its light left when the Universe was only 290 million years old! That means the light left the source LOOOONG before even our Milky Way was here! How amazing is that!

Elusive medium-size black holes may form in dense 'birthing nests'
A new simulation has shown elusive intermediate-mass black holes may form in dense globular clusters of millions of tightly packed stars, thanks to a chaotic collision chain.
How NASA's OSIRIS-APEX asteroid probe survived its 1st close encounter with the sun
OSIRIS-APEX emerged unscathed from its first of six close brushes with the sun, thanks to some clever engineering.
James Webb Space Telescope spots the 2 earliest galaxies ever seen (image)
James Webb Space Telescope has spotted the two earliest and most distant galaxies ever seen. One, JADES-GS-z14-0, is a massive and bright galaxy that existed just 300 million years after the Big Bang.
Pluto Has an Ocean of Liquid Water Surrounded by a 40-80 km Ice Shell
On July 14th, 2015, the New Horizons spacecraft conducted the first-ever flyby of Pluto, which once was (and to many, still is) the ninth planet of the Solar System. While the encounter was brief, the stunning images and volumes of data it obtained revealed a stunningly vibrant and dynamic world. In addition to Pluto’s heart, floating ice hills, nitrogen icebergs, and nitrogen winds, the New Horizons data also hinted at the existence of an ocean beneath Pluto’s icy crust. This effectively made Pluto (and its largest moon, Charon) members of the “Ocean Worlds” club.
Where are All the Primordial Black Holes?
The earliest black holes in the Universe called primordial black holes (PBHs), are strong contenders to help explain why the Universe is heavier than it looks. There’s only one problem: these miniature monsters haven’t exactly been observed—yet. But, when astronomers do find them, they might turn out to be part of the Universe’s dark matter component.
Boeing's Starliner rolls out to pad for June 1 astronaut launch (photos)
Boeing's Starliner capsule rolled out to the pad today (May 30) ahead of its first-ever astronaut launch, which is scheduled for June 1.
Japan loses contact with Akatsuki, humanity's only active Venus probe
The Japanese space agency has lost contact with its intrepid Venus orbiter, Akatsuki.
Solar Orbiter traces solar wind back to its mysterious source for 1st time
The European Space Agency's Solar Orbiter has, for the first time, traced solar wind in space to a specific location on our sun's surface.
A New Telescope Can Observe Even in Broad Daylight
Astronomy is a profession that, so far, has only been done at night, at least on Earth. Light from the Sun overwhelms any light from other stars, making it impractical for both professional and amateur astronomers to look at the stars during daytime. There are several disadvantages to this, not the least of which is that many potentially exciting parts of the sky aren’t visible at all for large chunks of the year as they pass too close to the Sun. To solve this, a team from Macquarie University, led by graduate student Sarah Caddy, developed a multi-camera system for a local telescope that allows them to observe during daytime.
Space debris from SpaceX Dragon capsule crashed in the North Carolina mountains. I had to go see it (video)
A large piece of debris was found on a mountainside in North Carolina last week, suspected to be left over from the reentry of SpaceX's Crew-7 mission to the International Space Station.
See the moon and Saturn meet in the night sky early on May 31
Saturn will appear just above the third quarter moon in the sky in the early hours of Friday (May 31).
Webb finds most distant known galaxy

Using the NASA/ESA/CSA James Webb Space Telescope, scientists have found a record-breaking galaxy observed only 290 million years after the big bang.
Next-Generation Radar Will Map Threatening Asteroids
When the Arecibo Observatory dish in Puerto Rico collapsed in 2020, astronomers lost a powerful radio telescope and a unique radar instrument to map the surfaces of asteroids and other planetary bodies. Fortunately, a new, next-generation radar system called ngRADAR is under development, to eventually be installed at the 100-meter (328 ft.) Green Bank Telescope (GBT) in West Virginia. It will be able to track and map asteroids, with the ability to observe 85% of the celestial sphere. It will also be able to study comets, moons and planets in our Solar System.
Astronaut's diary found among fallen Columbia space shuttle debris added to National Library of Israel
The journal pages of Israel's first astronaut have been added to the country's national library, more than 20 years after they were found among the debris from the tragedy that claimed his life.
James Webb Space Telescope finds a dusty skeleton in this starburst galaxy's closet
The James Webb Space Telescope caught the Magellanic-like galaxy NGC 4449 is undergoing an intense bout of star formation.
The 'Star Trek: Discovery' series finale is a mixed bag (review)
The "Star Trek: Discovery" finale seems to serve chiefly as a launch vehicle for the forthcoming Section 31 TV movie and Starfleet Academy series — and then there's all the other stuff.
Hot Gas is Being Vented Away from the Center of the Milky Way
Studying gas in the Universe is no easy task. We often look to ‘non-visible’ wavelengths of the electromagnetic spectrum such as X-rays. The Chandra X-Ray observatory has been observing a vent of hot gas blowing away from the centre of the Milky Way. Located about 26,000 light years away, the jet extends for hundreds of light years and is perpendicular to the disk of the Galaxy. It is now thought the gas has been forced away from the centre of the Milky Way because of a collision with cooler gas lying in its path and creating shockwaves.
How Much Water Would a Self-Sustaining Moonbase Need?
As humanity returns to the Moon in the next few years, they’re going to need water to survive. While resupplies from Earth would work for a time, eventually the lunar base would have to become self-sustaining? So, how much water would be required to make this happen? This is what a recently submitted study hopes to address as a team of researchers from Baylor University explored water management scenarios for a self-sustaining moonbase, including the appropriate location of the base and how the water would be extracted and treated for safe consumption using appropriate personnel.
Black Holes: Why study them? What makes them so fascinating?
Over the last few months, Universe Today has explored a plethora of scientific fields, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, cosmochemistry, meteorites, radio astronomy, extremophiles, and organic chemistry, and how these various disciplines help scientists and the public better understand our place in the cosmos.
