Earths days have been getting shorter since 2020. What has changed since then? Scientists are trying to understand what is going on. Is it something inside the planet? Although the July 9 event is due to the Moon. 

Curse of 2020? Time will change in 2029 because of mysterious factors

A cosmic giant that defies all laws of physics has been detected in the universe. Scientists are baffled by its discovery and are turning the tables around on known cosmological principles to know what it is how a mammoth structure that should not exist came into being.

GREAT WALL of universe: 10 billion light-years long cosmic monster detected in space should not exist

A cosmic body from another star system has entered Earth and is the largest one ever seen. In the previous decade, two other outer space objects were spotted in the solar system. One looked like an alien spaceship.

Interstellar visitor spotted is only the third: One of the other two appeared to be an 'alien vessel'

Meteorites from Mercury have never been found on Earth. But two pieces discovered in the Sahara desert might be remnants of an ancient Mercury, and are believed to be 4.5 billion years old. The presence of a mysterious material has created a little confusion. 

4.5-billion-year-old meteorites found in North Africa could be first pieces of Mercury on Earth

The supermassive black hole only reveals itself once every tens of thousands of years. It has gone rogue and is on a killing spree in its galaxy. Hubble Space Telescope caught it red handed devouring a star that was passing by. 

Invisible murderer in space reveals its location with a 'cosmic burp'. It is an anomaly

A rare astronomical event is unfolding as Saturn’s largest moon, Titan, casts its shadow on the planet’s surface. The next transit is on July 2, with more to follow until October. The event won’t repeat for 15 years — here’s how to watch it.

Black hole will cross through Saturn, but it is not a cosmic giant. Here is what it actually is

Comet C/2014 UN271 (Bernardinelli-Bernstein): The Oort cloud has sent its biggest comet yet towards the inner solar system, and it is travelling at an insane speed, releasing jets of carbon monoxide.

Giant comet from Oort cloud spotted moving at insane speed inside solar system. Will it reach Earth?

The Vera C. Rubin Observatory will find the ninth planet of the solar system, if one exists out there. It is also expected to discover a million asteroids in the next 10 years.

2,100 asteroids and 7 unknown objects were lurking near Earth. We have only now found them

NASA sent a satellite into space 60 years ago, which has been dead for a long time. But it suddenly transmitted a signal a few weeks back, shocking scientists on Earth. How was it possible?

Someone just contacted Earth, and it shouldn't have...because it is long dead

Ceres holds plenty of water to sustain life and can also act as propulsion fuel. A study has proposed building a space elevator on the dwarf planet to draw out this water.

30,000 km-long space elevator proposed on Ceres can solve two problems

Two supermassive black holes carrying the faint light of the Big Bang, 11.6 billion and 11.7 billion light-years away, have been observed shooting jets at great speeds that are extremely bright. 

Supermassive black holes from early universe seen shooting jets as bright as 10 trillion suns

The Vera C. Rubin Observatory in Chile houses the world's most powerful survey telescope with the largest digital camera ever built by humans, and it is about to drop its first pictures.

A comet, only one of five ever discovered, is defying the rules of space. It has a tail, with its water ice fizzling away despite being at a great distance from the Sun. 

Only 1 of 5: Comet discovered 2 billion kilometres from Sun is acting in a bizarre way

Two spacecraft, about 1.5 metres in size, synchronised so neatly in outer space that they managed to cover the Sun and create an artificial total solar eclipse.

Two spacecraft locked in a cosmic dance produce man-made Total Solar Eclipse

Strange radio signals that moved upwards from Earth were detected by a probe flying over Antarctica. Mysterious forces were likely at play here, or the signals were coming from deep space. 

Mysterious radio signals just tore through Antarctic ice. They could be coming from edge of universe

Planet Nine? Jupiter might be the goon of all planets. Its sheer size and gravitational pull likely once threw a planet out of the solar system. Where did it go? It might be the same planet scientists think is Planet Nine. 

One planet is missing from the solar system, blame 'Jumping Jupiter'

Voyager 1 and Voyager 2 encountered the “wall of fire”, burning up at 54,000-90,000 degrees Fahrenheit at the edge of the solar system. They both passed through to interstellar space.

Voyager spacecraft crossed 'wall of fire' to reach interstellar space. What is it?

The Moon might face fury from an asteroid in about eight years as the James Webb telescope discovers more about a space rock that once threatened Earth. 

What will happen on Dec 22, 2032? Not good things for our Moon, as scientists await major event

Starlink satellites are becoming a problem for scientists studying deep space as telescopes are unable to pick up faint radio signals coming from deep space, from the time the first stars were born.

10,000 times stronger: A leak in Starlink satellites is blocking signals from first stars of the universe

Black holes might just be wormholes, portals to the other side of the universe, a distant point that might not otherwise be accessible. Wormholes are also known as the Einstein-Rosen bridge.

Black holes or wormholes? Scientists find more proof that Einstein-Rosen bridge are real

A debris disk, or a protoplanetary disk, surrounds a young star and is filled with ice water, similar to what we have in the Kuiper Belt in our solar system.

Water bodies similar to that seen in Saturn's rings spotted in deep space

A bright yellow object appeared in the sky in 1408. Its appearance was different from everything else, leading ancient Chinese astronomers to make a record about it.    

1408 celestial mystery solved: Scientists reveal identity of 'Zhou Bo star' that disappeared after 10 days

The universe is humongous, and there is so much that we still do not know about it. Here are some cool facts about the universe we bet you probably did not know. 

Smell, colour and more: 5 facts about the universe we bet you did not know

The Milky Way was supposed to collide with Andromeda in the next 5 billion years. Turns out, scientists did not see the real culprit all this time which was hiding in plain sight. 

Not Andromeda, but the Milky Way will smash into a dwarf galaxy in 2 billion years
