Hubble Tension: NASA’s James Webb Telescope, Hubble Space Telescope to find out truth about Universe’s expansion rate

Scientists believe that our universe is expanding at a rapid rate, but there is a problem. A puzzle of sorts is there and it needs to be solved which is called the "Hubble Tension," it avers that the current rate of the expansion of the universe is faster than what astronomers expect it to be. Therefore, to understand the Universe's expansion rate, NASA's James Webb Telescope and Hubble Space Telescope have joined hands to find the inconsistency in measurements. The telescope's high-resolution data will help researchers study the puzzle and find out what really is happening with our Universe. Check out how cosmologists are planning to solve the errors and bring accuracy. Universe expansion rateAccording to a NASA report, the Hubble Space Telescope has been studying the current expansio...

Brightest object in Universe found: It’s “500 trillion times more luminous than the Sun”, experts say

Astronomers and researchers have been studying the Universe for decades with the help of advanced telescopes and equipment around the world. Now, with the help of the European Southern Observatory's (ESO) Very Large Telescope (VLT), astronomers have located the brightest object in Universe. It is a quasar. Experts believe that this is the most luminous object ever found in deep space. And the brightness does not stem from something ordinary. The quasar is said to be energized by what is reported to be the fastest-growing black hole on record. Know more about the brightest object in the Universe here.Brightest object in the Universe ever foundAccording to a study published in Nature Astronomy, the brightest quasar was spotted by ESO's Very Large Telescope (VLT) and it is said to be 500 ...

The biggest planet in the Universe? Scientist reveals the answer, but it will surprise you

In our solar system, we are aware that Jupiter is the biggest planet due to its size and mass however, beyond that there are several other planets that are far bigger. Unfortunately, under the current state of things, we cannot say for sure that there is one specific planet that is the biggest. In fact, there are several candidates there. The reason behind that is the uncertainty regarding their sizes and how we define a planet. Check out what Thayne Currie, an associate professor of physics and astronomy at the University of Texas, San Antonio said.What is the biggest planet in the universe?According to a Space.com report, Currie says that the largest planet ever known is called ROXs 42Bb. The size of the planet depends on numerous factors, however, planet ROXs 42Bb is known as the la...

Big find! NASA’s James Webb Telescope detects alternative form of carbon-based molecules

The apparently empty spaces in our universe are not truly devoid of matter. Instead, they are often occupied by clouds of gas and cosmic dust. These dust clouds consist of diverse-sized grains with different compositions, originating from various processes such as supernova events. That's why, this cosmic material plays a vital role in the evolution of the universe, acting as the building blocks for new stars and planets. In the latest development to detect these crucial grains, NASA's James Webb Space Telescope has detected carbon-rich dust grains in the early universe. To be precise, one billion years after the birth of the Universe!Similar observations of the carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs) have been observed in the much more recent Universe. ...

Euclid Mission: Bringing the dark universe to light

The Euclid mission, being undertaken by the European Space Agency (ESA), aims to illuminate the hidden aspects of our universe. It is expected to shed light on two enigmatic forces known as dark matter and dark energy. These entities, which remain undetectable through direct observation, exert significant influence on the behavior of galaxies, their rotation, and the expansion of the universe itself.To gain a deeper understanding of the nature of dark matter and dark energy, scientists require an instrument capable of closely examining the impact these forces have had on galaxies, galaxy clusters, and the overall expansion of the universe. And Euclid has emerged as the ideal solution for this pursuit. By generating a comprehensive 3D map of the universe, with the added dimension of tim...

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

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 in our...

James Webb Telescope looks back in time, finds oldest organic molecules ever seen

A groundbreaking study led by astronomers from Texas A&M University using NASA's James Webb Space Telescope (JWST) has unveiled the existence of the oldest known complex organic molecules in the universe. These carbon-based chemicals, called polycyclic aromatic hydrocarbons (PAHs), were found within an early galaxy that formed when the universe was only 10% of its current age.Unlike simple compounds such as water or carbon dioxide, the identified molecules are large and intricate, containing dozens or even hundreds of atoms. Similar to the ones found in smoke, soot, oil, coal deposits, and smog on Earth, these PAHs are commonly associated with tiny dust grains in space. The study's lead author, Justin Spilker, expressed his enthusiasm, stating that the discovery demonstrates the un...

NASA Astronomy Picture of the Day June 4, 2023: Color the Universe!

Today, NASA takes us on a quick visual journey of the galaxies, nebulae, Earth, planets, moon, and the vast depth of the cosmos through its "Astronomy Picture of the Day." However, instead of the stunning view of space or Earth, NASA has shared a task for you! If you love painting or colouring, this may interest you. “Wouldn't it be fun to colour in the universe? If you think so, please accept this famous astronomical illustration as a preliminary substitute,” NASA said while sharing an illustration.This is so because today's NASA Astronomy Picture of the Day is a famous Flammarion engraving. You will be surprised to know that this illustration of the sky has appeared on several occasions in the past 100 years. Who is the creator of this illustration? Sadly, the actual artist remains u...

NASA’s Roman Space Telescope will unravel the Universe like never before

Can the universe be rewinded? Going into the past is impossible. However, scientists and researchers keep trying to go back in time. It is now being said that a new simulation shows how NASA's Nancy Grace Roman Space Telescope will turn back the cosmic clock, unveiling the evolving universe in ways that have never been possible before when it launches by May 2027."With its ability to rapidly image enormous swaths of space, Roman will help us understand how the universe transformed from a primordial sea of charged particles to the intricate network of vast cosmic structures we see today," a report by NASA stated. Notably, combining Roman's large view with Hubble Space Telescope's broader wavelength coverage and James Webb Space Telescope's more detailed observations will offer a more c...

This 9th largest meteorite that ever struck Earth has something UNIQUE

Scientists have found evidence of two unique minerals in a massive 15000 kilogram meteorite which once hit the Earth. This big discovery can shed more light into the composition of the universe. The universe is unimaginably vast and we, the Earthlings, have only explored a small fraction of it. According to latest estimates, there are around 100-200 billion galaxies in the universe. And we have had a close view of less than 1 percent of our own galaxy. This opens up the question of how different the universe is compared to the solar system. Are carbon, nitrogen, oxygen the building blocks in other galaxies or are there entirely different sets of elements that dominate these worlds? This is why whenever a meteorite strikes the Earth, it is a golden opportunity for scientists to examin...
