Stellar Cradles and Graves Seen in Farthest Galaxy Ever July 14, 2023 — New observations have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years away.

One of this week's two new planets is TOI-700 e, a second planet in that system's habitable zone that shows how NASA's TESS is finding smaller and smaller worlds. Read the discovery paper by Gilbert et al. 2023 and the NASA Exoplanets media article.
Jul 24, 2023 - New measurements by NASA's James Webb Space Telescope's MIRI (Mid-Infrared Instrument) have detected water vapor in the system's inner disk, at distances of less than 100 million miles (160 million kilometers) from the star – the region where rocky, terrestrial planets may be forming.
The team searched for pairs of bright X-ray sources in colliding dwarf galaxies as evidence of two black holes, and discovered two examples. One pair is in the galaxy cluster Abell 133 located 760 million light-years from Earth, seen in the composite image on the left.
The nearest known black hole is Gaia BH1, which was discovered in September 2022 by a team led by Kareem El-Badry. Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus.
Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape. And then, at the center, is the singularity. That's the word we use to describe a point that is infinitely small and infinitely dense.
Unusual White Dwarf Star Is Made of Hydrogen on One Side and Helium on the Other. July 19, 2023 — In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of ...
James Webb Telescope Detects Impossible Ancient Light Questioning The Origins of The Universe. Ever since its launch, the James Webb Space Telescope has unveiled the universe like never before. It has shown us parts of the universe that lay hidden beneath layers of dust.
Detected: Most distant active supermassive black hole ever seen. The James Webb Space Telescope (JWST) has detected the most distant active supermassive black hole. The galaxy that hosts the ancient black hole, CEERS 1019, formed fairly early in the universe's history, just 570 million years after the Big Bang.
Question: Is there another planet like Earth? Answer: While there is no evidence of extraterrestrial life, scientists at NASA have recently discovered an earth-sized planet within the habitable zone of its star. The planet is called TOI 700 e.
Scientists have discovered another Earth-sized world that is orbiting around its star within the habitable zone and could have liquid water on its surface, according to NASA. The planet, called TOI 700 e, is about 95% of Earth's size and is likely rocky, the space agency announced in a post on Tuesday.
NASA scientists have identified a planet like Earth
Named TOI 700 e, this new planet orbits within its star's habitable zone, which also hints at the presence of water on its surface.
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive.
Astronomers are making waves with their recent findings on Proxima b - a 'highly habitable' exoplanet just a hop, skip, and a 4.2 light-year jump from Earth. Scientists believe this distant neighbor could be making serious splashes in the universe, boasting conditions suitable for sustaining oceans of liquid water.
A theory called "Big Bounce" proposes that the universe could collapse to the state where it began and then initiate another Big Bang, so in this way, the universe would last forever but would pass through phases of expansion (Big Bang) and contraction (Big Crunch).
“They revealed that they're trying to open a portal into another dimension.” But the researchers say that claim really is fiction.
Summary. There is no evidence of protogalaxy formation happening today. Protogalaxies are the precursor of galaxies and not seeing them suggests galaxy formation has come to an end. Scientists have, however, found tantalizing evidence of 'baby galaxies' relatively nearby.
By far the largest amount of matter is dark and consists of unknown particles. If that wasn't mysterious enough, the vacuum of empty space is filled with a mysterious dark energy that accelerates the expansion of the Universe.
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
Moreover, new SpaceTech trends, like smart propulsion, space robotics, and space traffic management are also gaining traction in the space industry. Together with increasing private investment in the industry, startups develop technologies to ease movement, operations, and communications between earth and space.
We might be the product of another, older universe. Call it our mother universe. The seed this mother universe forged inside a black hole may have had its big bounce 13.8 billion years ago, and even though our universe has been rapidly expanding ever since, we could still be hidden behind a black hole's event horizon.
By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside.
From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies. According to Einstein's theory, time and space, in a way, trade places inside the hole.
