The smallest moon ever detected around Uranus and two around Neptune

[ad_1] Astronomers have recently made an intriguing discovery in our solar system, uncovering two tiny moons circling Neptune and one orbiting Uranus. These newfound celestial companions bring the total count of known moons around these gas giants to 16 for Neptune and 28 for Uranus.The most remarkable of these discoveries is Uranus' new moon, believed to be the smallest ever detected around the ice giant. Measuring a mere 5 miles (8 kilometers) in width, this diminutive moon completes a single orbit around Uranus every 680 days. To put its size into perspective, it's even smaller than Mars' moon Deimos, one of the tiniest known moons in our solar system, according to Carnegie Institution for Science. Currently designated as "S/2023 U1," the Uranian moon awaits an official name, likely ...

Want to go to Mars? Know the solar flare danger that can even kill you

[ad_1] After yesterday's success of the Chandrayaan-3 mission, the excitement in the astronomy community is at an all-time high. Many are already wondering about other new achievements India and the world can unlock. And among the huge bucket list of ideas about space exploration, one thing has always remained on top - a manned mission to Mars could pave the way for building a colony on the red planet. However, a NASA scientist has warned us that this dream may just not be possible in the near future with the current technology that we have. Why? It's because the radiation from solar flares and coronal mass ejections (CME) will kill us long before we ever reach Mars. NASA scientist Dr. Michelle Thaller spoke with The US Sun and explained that the technology we have at the moment is simp...

Bad news! Voyager 2 makes last call? NASA spacecraft lost out in space

[ad_1] Voyager 2 is a space probe that was sent to explore planets far away in our solar system and it has reached the a region called interstellar space. Voyager 2 is the 2nd farthest human artefact from Earth after Voyager 1. But now, NASA is worried because something has gone wrong. The spacecraft's antenna has moved by two degrees due to a routine command glitch, and this little change has caused big trouble. Voyager 2 can't talk to Earth anymore or send back any data. The Deep Space Network's antennas on Earth can't reach it either. Voyager 2 is currently 19,935,511,250 kilometers away from Earth.NASA fears that this might be the end of communication with Voyager 2. It's getting farther and farther away from Earth, and it may never be able to talk to us again. Right now, it's about...

Astronomers discover a gigantic mirror-like planet with clouds made of metal

[ad_1] Astronomers have made a remarkable discovery using data from the European Space Agency's Cheops satellite. They have found a planet that defies expectations and, according to them, should not even exist. It is known as LTT9779 b. This Neptune-sized exoplanet orbits very close to its host star, completing a full orbit in less than a day.LTT9779 b- The Mirror PlanetLTT9779 b is essentially a colossal mirror in space, reflecting an astonishing 80% of the light it receives from its nearby star. For comparison, Venus, with its thick cloud layer, reflects only 75% of the Sun's light, while Earth reflects a mere 30%. The reason for this planet's incredible reflectivity lies in its atmosphere, which is laden with thick metal clouds, majorly composed of silicate (similar to sand and glass...

Spectacular Planetary Parade today; here’s how to watch it

[ad_1] This weekend, get ready for a special celestial event called a 'planetary parade' in the night sky. It's a rare occurrence when five planets gather at the same time. This exciting planetary alignment will happen at sunrise on Saturday, offering a stunning spectacle.Which planets can you see?Today, you will be able to witness the alignment of five planets: Saturn, Neptune, Jupiter, Uranus, and Mercury. While Saturn, Jupiter, and Mercury will be relatively easy to spot, Neptune and Uranus might be a bit challenging to see without binoculars. Jupiter, in particular, will be the brightest object in the morning sky until the sun rises, making it quite noticeable. However, the other planets will appear fainter. Why do the planets line up?Contrary to what movies often show, the planets ...

NASA Astronomy Picture of the Day 10 June 2023: Mars with Beehive!

[ad_1] The month of June will be quite interesting for skywatchers! Mars and Venus will be seen gradually approaching each other in the western sky after sunset. Adjacent to these celestial wonders is the captivating blue-white star known as Regulus, which serves as the heart of the constellation Leo, the lion. Furthermore, slowly and gradually, from the 20th to the 22nd of June, the crescent Moon will pass through this celestial region, creating a particularly spectacular view at dusk on June 21st.Today's NASA Astronomy Picture of the Day is a stunning image of the red planet Mars near the stars of the open cluster Messier 44. In this month, the evening skies of planet Earth will also showcase Mars and Venus as prominent celestial guests. After sunset, these two celestial bodies will s...

NASA Astronomy Picture of the Day 27 May 2023: When Voyager snapped Neptune and Triton together

[ad_1] Among Neptune's 14 moons, Triton stands out as the largest. What makes it truly remarkable is its unconventional behaviour – it is the only moon in our solar system that orbits in a direction opposite to its planet's rotation. According to scientists, Triton is believed to be a celestial body that originally belonged to the Kuiper Belt — a region of space beyond Neptune. NASA says that there is a possibility that it may have been captured by Neptune's gravitational pull millions of years ago. Interestingly, Triton shares numerous similarities with Pluto, which is the most prominent representative of the Kuiper Belt.Today's NASA Astronomy Picture of the Day is a crescent phase Neptune with its moon Triton. In 1989, as the Voyager 2 spacecraft gracefully journeyed through the outer...

Telescope captures mini neptune.The James Webb Space Telescope, rthe world's leading space science observatory, has made a significant discovery. It has snapped a mysterious planet outside our solar system known as GJ1214b. The telescope's amazing capabilities allow it to peer back into time into the universe's past, reaching as far back as approximately 250 million years and potentially, even up to 100 million years following the Big Bang, when the formation of the first stars and galaxies began. GJ1214b, the planet under scrutiny, possesses a distinctive atmosphere characterised by a steamy enviro...

Mysterious RED asteroids found around Neptune could reveal big secrets

[ad_1] The fascination of scientists with understanding the origin of the solar system is never ending. Recently, in an attempt to uncover the secrets around it, NASA sent its OSIRIS-REx spacecraft to collect samples from asteroid Bennu, which will reach Earth in the later half of this year. And now, out of the same curiosity, astronomers have turned to Neptune to understand this grand mystery. Not exactly Neptune, but the area surrounding it, which is filled with mysterious red asteroids. A new study claims that it could reveal how our solar system came to be.The study was conducted by NASA astronomer Bryce Bolin and has been published in the journal Monthly Notices of the Royal Astronomical Society: Letters. The study focuses on the red color of the asteroids and highlights that the c...

Amazing! NASA’s James Webb Telescope captures clearest view of Neptune rings in 30 years

[ad_1] After more than 30 years, the clearest view of Neptune's ring has been captured by NASA's James Webb Telescope. Here is all you need to know. Another amazing image captured by NASA's James Webb Telescope is out. It has captured the clearest image of Neptune's rings in more than 30 years and also reveals the ice giant in a whole new light. Informing about the same, NASA Webb Telescope tweeted, "Hey Neptune. Did you ring? Webb's latest image is the clearest look at Neptune's rings in 30+ years, and our first time seeing them in infrared light. Take in Webb's ghostly, ethereal views of the planet and its dust bands, rings and moons." In addition to several bright, narrow rings, the Webb image clearly shows Neptune's faint...
