A new definition of what a planet is, has been proposed by planetary scientists to replace the one which already exists, and is seen as outdated and sun-centric by many experts.

Scientists plan to revisit definition of planet but Pluto still remains out of list

It is very well known that there are eight planets in our Solar System and then a dwarf planet - Pluto. But now the astronomers are suspecting there is a 7 per cent chance that another planet is hiding in the Oort cloud near Earth.

Unknown planet lurking in our Solar System? Scientists say Earth may have a new neighbour

It has been taught to us from school days that Earth orbits around the Sun, which results in the cycle of day and night. However, if we try to understand the movement of Earth currently in the Solar System from the point of view of scientists, our planet is not currently orbiting the Sun.

Strictly speaking, Earth is not revolving around the Sun currently. Here's what it means

The particles which are flying around planet Uranus are facing "traffic jams". Now, scientists have found the reason behind this weird scenario in the cosmic world.

Uranus is facing 'traffic jams' in the cosmic world. Here's why

The idea of life existing elsewhere in the solar system has always captured the imagination of mankind. Many years, Mars has been considered the ideal candidate by scientists to set up a future space colony.

Recent research has pointed out that the early shape of our Solar System was more like a doughnut than the flat disk we recognise at present. The discovery comes from an in-depth study of iron meteorites originating from the outer reaches of the Solar System.

Scientists suggest our Solar System was shaped like donut in the beginning

If astronomers succeed in discovering the elusive Planet Nine, a hypothetical world believed to be lurking in the outer reaches of our solar system, sending a spacecraft to visit this distant world would be an immense challenge.

On June 13, 1983, NASA'S Pioneer 10 became the first man-made object to cross the solar system. Here's a Gravitas recall.

Mars is believed to be more prone to devastation from asteroids than what was believed earlier. Studies suggest that this may pose a risk to future Mars missions that have been planned to investigate whether Mars can be an alternative for human inhabitation.

Asteroids can cause catastrophe on Mars and scientists are worried. Here's why

Scientists have observed carbon dioxide and carbon monoxide ices in the far reaches of our solar system on trans-Neptunian objects (TNOs) for the first time. The observations were made using the infrared spectral capabilities of the James Webb Space Telescope (JWST), which is the largest and most powerful telescope ever launched into space.

NASA's Juno mission clicked captivating views of Jupiter during its 59th close flyby of the planet on March 7, 2024, according to an official readout along with images captured by the mission.

Researchers have come across a new exoplanet TOI-6713.01 located approximately 66 light-years away from Earth, reports said citing a recent study published in The Astronomical Journal.

Furious volcanic eruptions on exoplanet termed 'lo on steroids' make it hotter than some stars

The James Webb space telescope, which is the most powerful space telescope ever built, has discovered what is being hailed as the “strongest, most promising sign” of life on another planet. Nasa now plans to embark on a new mission to study this exciting sign of alien life found on the exoplanet k2-18b planet which is '124 light-years away'. Watch this report to know how Phytoplanktons found in our oceans is guiding the search for extraterrestrial life.

In the search for a mysterious planet in our solar system, scientists have now discovered more evidence that hints at the existence of "Planet Nine" or "Planet X" in our solar system.

A ninth planet? Scientists are convinced that our solar system might be hosting a 'Planet X'

Scientists have finally found out what's happening to the National Aeronautics and Space Administration (NASA)'s pioneering Voyager 1 spacecraft, and what's behind the gibberish sounds coming from it in November.

For years, we have known that our Earth will one day be swallowed by the Sun as it will balloon because of its extinguishing fuel. However, a new study has highlighted the death of Earth and other planets may be more chaotic and violent than ever imagined by human civilisation.

A violent end awaits our solar system as all planets will be 'crushed' to dust one day

Scientists for the first time have observed a rare phenomenon, called the "glory effect" on a planet that is outside our solar system. The glory effect is a set of rainbow-like colorful concentric rings which occur only under peculiar conditions.

In 1930 Pluto was long considered our Solar System's ninth planet but then in 2006 the international astronomical Union categorized it as a dwarf planet due to its tiny size. Watch in for more details!

Pluto: Should 'Pluto' be a planet again? The debate rages on

In what seems like a fascinating piece of story straight out of a space-based film, scientists are now busy charting the best way out of our solar system. Is it even possible to travel out of our solar system?

Scientists find best way to move out of our solar system. Here's what the cosmic journey looks like

Discovered in 1930 Pluto was long considered our Solar System's ninth planet but then in 2006 the International Astronomical Union categorized it as a dwarf planet due to its tiny size. Our next report tells you how there is now a call to restore Pluto to its original status of a bonafide planet.

Calls to make Pluto a planet again

Pluto: A fascinating icy world beyond planetary status

Arizona, situated in the southwestern United States, has officially designated Pluto as its "state planet," despite the International Astronomical Union's decision in 2006 to reclassify Pluto as a "dwarf planet," and removing its status as an official planet.

This US state has declared Pluto as its ‘official state planet’

Jupiter's moon Io was observed in 1979 in detail for the first time during NASA's Voyager 1 and Voyager 2 missions. These spacecraft provided the first close-up images and scientific data of Io and the other Galilean moons.

New Horizons spacecraft made new and stunning observations which suggest that the Kuiper Belt might stretch much farther out than scientists previously thought. The Kuiper Belt is the vast, distant outer zone of our solar system populated by hundreds of thousands of icy, rocky planetary building blocks.
