Galaxy cluster MACS0416.
Using infrared observations from Webb and visible-light details from Hubble, astronomers stitched together an astonishing, panchromatic image of the MACS0416 cluster located approximately “4.3 billion light-years from Earth, meaning that the light from it that we see now left the cluster shortly after the formation of our solar system.
Our solar system is nearly 4.6 billion years old.

Nasa's Roman Mission !
This image represents a computer-generated simulation of the observations made by the Roman Space Telescope directed towards the heart of our galaxy. It covers just a tiny fraction, less than 1 percent, of the complete extent of Roman’s survey of the galactic bulge.
The simulated stars in this image were generated based on data from the Besançon Galactic Model.

CTB 1 supernova,
NASA’s Fermi Satellite Clocks ‘Cannonball’ Pulsar Speeding Through Space !
The remnant of the supernova resembles a ghostly bubble in this image, which combines new 1.5 gigahertz observations from the Very Large Array (VLA) radio telescope (orange, near center) with older observations from the Dominion Radio Astrophysical Observatory’s Canadian Galactic Plane Survey (1.42 gigahertz, magenta and yellow; 408 megahertz, green) and infrared data (blue).
The VLA data clearly reveal the straight, glowing trail from pulsar J0002+6216 and the curved rim of the remnant’s shell. CTB 1 is about half a degree across, the apparent size of a full Moon.

White Dwarf
A White Dwarf is what remains of a star like our Sun after it sheds its outer layers and stops burning fuel through nuclear fusion.

The Sgr A* black hole!
It’s the first image of our Milky Way galaxy’s hometown black hole, captured by the EHT. Like many of its kind, our very own supermassive black hole has such intense gravity that it bends space and time, forming a torus of light with an infinite void in the center.
The mass of this entity, known as Sagittarius A* or Sgr A* due to its proximity to the Sagittarius constellation when seen from Earth, is equal to more than four million suns, and it reaches temperatures in the trillions of degrees. It’s also known to casually consume stars. Luckily, if anything can hold up against the sucking void of eternal space-time, it is the confidence of a Sagittarius...

NASA’s IXPE Sends First Science Image!
All instruments are functioning well aboard the observatory, which is on a quest to study some of the most mysterious and extreme objects in the universe.
IXPE first focused its X-ray eyes on Cassiopeia A, an object consisting of the remains of a star that exploded in the 17th century. The shock waves from the explosion have swept up surrounding gas, heating it to high temperatures and accelerating cosmic ray particles to make a cloud that glows in X-ray light.
Other telescopes have studied Cassiopeia A before, but IXPE will allow researchers to examine it in a new way.
This image of the supernova remnant Cassiopeia A combines some of the first X-ray data collected by NASA’s Imaging X-ray Polarimetry Explorer, shown in magenta, with high-energy X-ray data from NASA’s Chandra X-Ray Observatory, in blue.

Helium gas coughs
U Camelopardalis, or U Cam for short, is a star nearing the end of its life located in the Giraffe constellation near the celestial North Pole. As it begins to run low on fuel, instability within the star's core creates coughs of helium gas every few thousand years. This one was captured by Hubble in 2012.

Star cluster NGC 2060
This composite image, released as part of Hubble's 22nd launch anniversary in 2012, shows the star cluster NGC 2060, located in the heart of the Tarantula Nebula some 170,000 light-years away, in the Large Magellanic Cloud — a satellite galaxy of our Milky Way. The cluster was created by a supernova that exploded about 10,000 years ago, according to NASA.

The ant nebula
From ground-based telescopes, this cosmic object — the glowing remains of a dying, sun-like star — resembles the head and thorax of an ant. The image, released in 2001, of the so-called ant nebula, otherwise known as Menzel 3, shows far greater detail revealing a pair of fiery lobes protruding from the dying star.
