How Hot Was the Universe 7 Billion Years Ago? Scientists Now Have an Answer
Japanese astronomers using ALMA data have found the universe was about twice as hot 7 billion years ago, with a temperature of 5.13 K compared to today’s 2.7 K. The finding aligns perfectly with Big Bang predictions that the Universe cools as it expands, providing the most precise mid-epoch measurement yet and reinforcing confidence in standard c...

New Interstellar Object 3I/ATLAS Could Reveal Secrets of Distant Worlds
Astronomers have confirmed the arrival of 3I/ATLAS, only the third interstellar object ever spotted in our solar system. First seen on July 1, 2025, by the ATLAS survey team in Chile, it was quickly identified by its unusual hyperbolic orbit and comet-like tail. Larger and brighter than either 1I/ʻOumuamua or 2I/Borisov, 3I/ATLAS is estimated to b...

New Interstellar Comet 3I/ATLAS Speeds Through Solar System
Astronomers have identified 3I/ATLAS as the third confirmed interstellar comet, racing through the solar system at 68 km/s. Discovered on July 1, it will pass near the sun in October. Skywatchers can view this rare object live online tonight, thanks to a live stream by the Virtual Telescope Project using observatories in Italy.

Mysterious Icy Objects Found in Milky Way Baffle Astronomers: Everything You Need to Know
Astronomers have identified mysterious icy objects in the outer Milky Way, raising questions about their nature. These structures, composed of ice and gas, are located in a region where star formation is rare. Despite early detections dating back to 2006-2011, recent observations using the AKARI space telescope and the ALMA array in Chile have prov...

Astronomers Confirm Brown Dwarf Gliese 229B as Twin Pair Orbiting in 12 Days
Scientists have discovered that Gliese 229B, the first brown dwarf discovered 30 years ago, is actually two brown dwarfs orbiting close to each other. This unexpected find was made using the Very Large Telescope in Chile, solving a long-standing puzzle about the object's dim appearance. The twins, Gliese 229Ba and Gliese 229Bb, orbit each other in ...

Gemini South’s GHOST Spectrograph Captures Optical Light Spectrum From Chemically Complex Star
The Gemini South telescope, one of the world’s most powerful optical-Infrared telescopes located in Chile, has captured its first light image of a chemically complex star. The telescope was equipped with the GHOST, or the Gemini High-Resolution Optical SpecTrograph, allowing it to capture detailed images of celestial bodies.
