NASA Shares Planetary Defense Strategy to Protect Earth From Potential Asteroid Strikes
NASA and international scientists closely tracked asteroid 2024 YR4, which initially showed a rare 3 percent collision probability with Earth. Although the threat has now diminished, the incident highlights the importance of asteroid surveillance, open data, and upcoming space missions like NEO Surveyor.

Mysterious Planetary-Mass Objects May Form in Young Star System Clashes
Recent research challenges traditional views on planetary-mass objects, suggesting they may form through violent interactions between young star systems rather than standard planetary or stellar processes. Simulations indicate these clashes create dense gas filaments that evolve into free-floating objects, often in binary pairs. This discovery expl...

'Kiss And Capture': Study Explains How Pluto's Largest Moon Was Formed
A new study suggests Pluto's largest moon, Charon, may have formed through a unique "kiss and capture" event billions of years ago.

New "Kiss-and-Capture" Theory Explains Pluto's Formation of Largest Moon, Charon
A new theory proposes that Pluto’s largest moon, Charon, was formed billions of years ago through a rare "kiss-and-capture" collision in the Kuiper Belt. This process involves two icy bodies briefly merging and then separating, leaving Charon in a stable orbit around Pluto. Unlike traditional collision models, this event challenges previous theor...

New Study Suggests the Moon Is 100 Million Years Older Than Previously Thought
Recent findings indicate the Moon might be over 100 million years older than prior estimates. A new study proposes that tidal forces caused intense heating and surface remelting around 4.35 billion years ago, resetting the apparent age of lunar rocks. These insights support the idea that massive collisions formed the Moon much earlier than previous...

Apophis Asteroid Flyby in 2029: Earth's Gravitational May Impact Asteroid's Surface
Asteroid 99942 Apophis, named after the ancient Egyptian god of darkness, is set to pass incredibly close to Earth in 2029, at just 32,000 km. While there is no risk of a collision, scientists are keen to study the asteroid’s interaction with Earth's gravity. Research led by planetary scientist Ronald Ballouz suggests that this flyby may cause si...

Taurid Meteor Stream Unlikely to Contain Dangerous Asteroids, New Study Suggests
A recent study led by Quanzhi Ye, an astronomer at the University of Maryland, reveals that the Taurid Meteoroid Complex, a debris stream linked to past Earth impacts, poses less danger than previously thought. Ye's team found fewer large asteroids in the stream, reducing the risk of a catastrophic collision with Earth. While these findings offer r...

Asteroid 2007 FT3 Poses No Threat To Earth, NASA Confirms
NASA assures that an 'unlocated' asteroid, comparable in size to the Shard, will not collide with Earth on October 5th.

NASA's Hubble Telescope Captures Collision of DART With Asteroid Dimorphos
National Aeronautics and Space Administration's Hubble Space Telescope captured a series of photos of asteroid Dimorphos when it was deliberately hit by a 1,200-pound NASA spacecraft called DART on September 26, 2022, according to their statement. Hubble's time-lapse movie of the aftermath of DART's collision reveals surprising and remarkable, hour...

NASA DART Spacecraft Successfully Slams Into Asteroid Dimorphos in First Planetary Defence Test
NASA on Monday successfully crashed into an asteroid in the world's first test of a planetary defense system, as the US space agency continues to work on technology to prevent potential meteorite collisions with Earth, that could threaten life on the planet. The DART spacecraft was launched by a SpaceX rocket in November 2021, and made most of its ...

Collision With Moon-Sized Body Likely Delivered Gold To Earth, Says Study
A large Moon-sized planetary body penetrated all the way down to the Earth's core during the early days of our home planet's formation, delivering in the process precious metals such as gold and platinum, suggests a new study.

Planetary Collision With Earth Created Moon: Study
The Moon was formed when a planet-sized object struck the infant Earth some 4.5 billion years ago, a new study has found, confirming the most prevalent hypothesis on the formation of the lunar body.

What Collisions in Solar System Did to Mercury
The planet Mercury and other unusually metal-rich objects in the solar system may be relics left behind by collisions in the early solar system that built the other planets, says a study.
