Dwarf planet Ceres may be hundreds of millions of miles from Jupiter, and even farther from Saturn, but the tremendous influence of gravity from these gas giants has an appreciable effect on Ceres’ orientation. In a new study, researchers from NASA’s Dawn mission calculate that the axial tilt of Ceres —

Scientists have located an impact crater linked to powerful tsunamis that swept across part of ancient Mars.

The team believe an asteroid triggered 150m-high waves when it plunged into an ocean thought to have existed on northern Mars three billion years ago.

Under US President Donald Trump’s proposed budget, NASA’s funding would stay largely intact but the space agency would abandon plans to lasso an asteroid, along with four Earth and climate missions.

The 2018 budget — which must be approved by Congress —

The description of a “signum in coelo” included in the Chronicon Novalicensis reminds me in some ways what happened on Feb. 15th, 2013 over Chelybinsk:

“Karolus Manuus Rex Bajoariorum  ingressus est in Italiam cum infinita populi multitudine,

After sending a probe to Mars in 2020, China plans to explore three asteroids and land on one of them to conduct scientific research, according to a Chinese asteroid research expert.

The “China’s Space Activities in 2016” white paper,

A car-sized asteroid narrowly missed the Earth on Monday, January 30, six days after another asteroid the size of a house had a similar near-miss, and ten days after a third passed by that was about the size of a killer whale.

Asteroids on the main belt, situated between Mars and Jupiter, move around the Sun in quasi circular orbits, so they do not undergo the temperature changes which, in comets, produce the characteristic tails. Nevertheless, some twenty cases have been documented of asteroids which,

A small near-Earth asteroid less than 3 meters (10 feet) across whizzed safely past Earth today at a distance so close that it passed well inside the ring of geosynchronous satellites. Designated 2017 EA, the asteroid made its closest approach to Earth at 6:04 a.m.

As 2013’s Chelyabinsk meteor proved, an asteroid doesn’t have to make direct contact with Earth’s surface to do considerable damage.

The Chelyabinsk meteor, which became a fireball brighter than the sun, a superbolide, as it entered Earth’s atmosphere above Russia,

NASA’s Dawn mission has found evidence for organic material on Ceres, a dwarf planet and the largest body in the main asteroid belt between Mars and Jupiter. Scientists using the spacecraft’s visible and infrared mapping spectrometer (VIR) detected the material in and around a northern-hemisphere crater called Ernutet.
