You’re looking at the coldest place ever found in the universe. It’s the Boomerang Nebula, a young planetary nebula located 5,000 light-years from Earth in the constellation Centaurus. The temperature here is -272.15°C or -457.87°F. That’s just one kelvin above absolute zero, the temperature at which all atomic motion stops. Furthermore, this region is even colder than the cosmic microwave background radiation, which is the leftover heat from the Big Bang. The Boomerang Nebula gets its name from its distinctive shape, which resembles a boomerang. The nebula, spanning 10 light years, is formed by the outflow of gas from a dying star. As the gas expands, it cools down. The nebula is so cold because it is expanding very rapidly at a rate of around 160,000 km/hr. Astronomers believe it will continue to cool down for the next few thousand years.

NASA has announced that the Sun has reached its peak in its 11-year cycle. We have officially entered the solar maximum period of Solar Cycle 25. So, what will the solar maximum do to our planet in the coming months? How long will this period of heightened solar activity last? Finally, and most importantly, will this increase the average global temperature and warm our planet over the next year?

Our galaxy is positioned near the center of a massive cosmic void known as the KBC void or the Local Hole. This void, which stretches an incredible 2 billion light-years across, challenges some of the most basic ideas in cosmology. The existence of such a vast empty space raises big questions about the Big Bang, how galaxies are spread out, and the very nature of the universe’s expansion. However, the most intriguing part is that this void could help explain two of astronomy’s biggest puzzles: the Hubble Tension and the Fermi Paradox.

,1,The James Webb Space Telescope has made a record-breaking observation in deep space. The infrared observatory has given astronomers their first detailed glimpse of supernovae from when our universe was just a small fraction of its current age.
Within a patch of sky about the size of a rice grain held at arm's length, Webb has discovered at least 80 supernovae, increasing the number of known supernovae in the early universe by tenfold. Some of these newly found supernovae are the farthest we've ever seen, including ones that help us measure how fast the universe is expanding.
To discover supernovae, the team compared several images taken up to a year apart, searching for sources that either appeared or vanished. These objects, which change in brightness over time, are known as transients. Supernovae are a specific type of transient. The team spent over 100 hours of Webb's observing time on each image, and the results have opened a new window into the early universe.

,1,Astronomers have found the strongest statistical evidence of Planet 9, the hidden planet of our solar system believed to be lurking in the outskirts of the solar system. The possibility of the existence of Planet 9 has long intrigued scientists. Some researchers believe it might have been a rogue planet captured by our Sun's gravity, while others think it could have formed from the same disk of gas and dust as the other planets. If Planet 9 exists, it is believed to be ten times more massive than Earth and orbit the Sun at a distance of 400 to 800 Astronomical Units, which is 400 to 800 times the distance between the Earth and the Sun.
Astronomers have been eagerly hunting for clues, using powerful telescopes and advanced computer models to track its influence. After years of watching the sky, solving mathematical equations, and running complex computer simulations, they now have the strongest evidence yet that Planet 9 really exists. This discovery introduces an exciting plot twist in the story of the hidden planet.
