The recent release of a captivating image by the James Webb Space Telescope (JWST) showcases the remarkable sight of new sun-like stars emerging in the Rho Ophiuchi region, which happens to be the nearest area where stars are currently being formed.

The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust.
This image is part of a collection of Hubble observations designed to better understand our nearby galactic neighbors. The observations aim to resolve the brightest stars and basic properties of every known galaxy within 10 megaparsecs. A parsec is a unit used by astronomers to measure the vast distances to other galaxies β 10 megaparsecs translates to 32 million light-years β and makes astronomical distances easier to handle. For example, the nearest star to the Sun, Proxima Centauri, is about 1.3 parsecs away. In everyday units this is a staggering 25 trillion miles (40 trillion km)!
The program to capture all of our neighboring galaxies was designed to use the 2-3% of Hubble time available between observations. Itβs inefficient for Hubble to make back-to-back observations of objects that are in opposite parts of the sky. Observing programs like the one that captured ESO 174-1 fill the gaps between other observations. This way the telescope can move gradually from one observation to another, while still collecting data. These fill-in observing programs make the most out of every last minute of Hubbleβs observing time.

πWebb Makes First Detection of Crucial Carbon Molecule:
A team of international scientists has used NASAβs James Webb Space Telescope to detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.
Carbon compounds form the foundations of all known life, and as such are particularly interesting to scientists working to understand both how life developed on Earth, and how it could potentially develop elsewhere in our universe. The study of interstellar organic (carbon-containing) chemistry, which Webb is opening in new ways, is an area of keen fascination to many astronomers.
3 panels, left, nebula with two stars and multi-hued clouds divided diagonally. Top-right of same area, but upper left region is red, yellow and green, the lower right region is dark blue. Lower right, image of a yellow and orange blob.
These Webb images show a part of the Orion Nebula known as the Orion Bar. The largest image, on the left, is from Webbβs NIRCam (Near-Infrared Camera) instrument. At upper right, the telescope is focused on a smaller area using Webbβs MIRI (Mid-Infrared Instrument). At the very center of the MIRI area is a young star system with a protoplanetary disk named d203-506. The pullout at the bottom right displays a combined NIRCam and MIRI image of this young system.

The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/ESA Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is, like all globular clusters, a densely populated region of tens of thousands of stars.
This image of NGC 6544 combines data from two of Hubbleβs instruments, the Advanced Camera for Surveys and Wide Field Camera 3, as well as two separate astronomical observations. The first observation was designed to find a visible counterpart to the radio pulsar discovered in NGC 6544. A pulsar is the rapidly spinning remnant of a dead star, emitting twin beams of electromagnetic radiation like a vast astronomical lighthouse. This pulsar rotates particularly quickly, and astronomers turned to Hubble to help determine how this object evolved in NGC 6544.
The second observation which contributed data to this image was also designed to find the visible counterparts of objects detected at other electromagnetic wavelengths. Instead of matching up sources to a pulsar, however, astronomers used Hubble to search for the counterparts of faint X-ray sources. Their observations could help explain how clusters like NGC 6544 change over time.

π¨URGENT: An asteroid, comparable in size to a house, was recently detected and will come remarkably close to Earth on June 25. It will approach at a distance equivalent to approximately 60% of the average separation between the Earth and the Moon.

Breaking News:In a significant development, astronomers have reported that a distant galaxy's black hole, emitting a stream of ionized radiation, has altered its trajectory and is currently directed towards Earth. This phenomenon is being described as an extraordinary instance of jet reorientation.

Nasa:During the Skylab 2 crew's final fly-around inspection on June 22, 1973, they saw this overhead view of the Skylab space station. It has a single solar panel and a parasol solar shield, rigged to replace the micrometeoroid shield. A mishap in the original Skylab 1 liftoff and orbital insertion resulted in damage: both the second solar panel and the micrometeoroid shield were torn away.
