‘Alien comet’ visitor has weird composition

The first known comet to visit us from another star system has an unusual make-up, according to new research.

The interstellar comet 2I/Borisov was detected in our Solar System last year.

This mysterious visitor from the depths of space has provided astronomers with an unprecedented opportunity to study how different it is from comets that have been formed around the Sun.

When comets break up, the fragments can be devastating if they hit the Earth

Comet breakups are a timely topic right now. The interstellar comet 2I/Borisov just broke into at least two pieces. And though that comet is speeding out of the Solar System, never to be seen again, most of them don’t leave the Solar System.

One step closer to touching Asteroid Bennu

After the successful completion of its “Checkpoint” rehearsal, NASA’s first asteroid-sampling spacecraft is one step closer to touching down on asteroid Bennu. Yesterday, NASA’s OSIRIS-REx spacecraft performed the first practice run of its sample collection sequence, reaching an approximate altitude of 246 feet (75 meters) over site Nightingale before executing a back-away burn from the asteroid.

Rehearsal Time for NASA’s Asteroid Sampling Spacecraft

In August, a robotic spacecraft will make NASA’s first-ever attempt to descend to the surface of an asteroid, collect a sample, and ultimately bring it safely back to Earth. In order to achieve this challenging feat, the OSIRIS-REx mission team devised new techniques to operate in asteroid Bennu’s microgravity environment –

Researchers zero in on Near-Earth Asteroid deflection simulations ahead of breakthrough mission

The simulation tests are currently in full swing, as the astrophysicist community is looking forward to the so-called Double Asteroid Redirection Test (DART) mission – the first kinetic impact deflection probe to be carried out on a near-Earth asteroid.

Researchers at the Lawrence Livermore National Laboratory (LLNL) in California have moved further in their efforts to simulate how they might deflect celestial bodies potentially heading to and potentially hitting the Earth (although the latter is highly improbable),

Killer asteroid hunt in jeopardy, new study claims

SpaceX, the largest commercial satellite constellation operator in the world, has ambitious plans of installing 12,000 satellites in low-orbit over a span of several years, as part of its Starlink project to provide low-cost broadband internet service.

A well-known astronomer and satellite tracker has voiced concerns that efforts to scan the skies for potentially dangerous near-Earth asteroids might be in jeopardy due to ambitious plans by SpaceX to deploy over 12,000 satellites in low-Earth orbit over the next several years.

Researchers find new minor planets beyond Neptune

Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series,

Fire from the sky

Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to the moment ancient nomadic people first settled down and started cultivating crops. A large mound marks the settlement,

Have we really found an alien protein inside a meteorite?

A team of researchers claim to have found a protein inside a meteorite. It would be the first protein ever discovered from beyond Earth, though not an indication of alien life – and other scientists are sceptical the analysis really found anything at all.

An iron-clad asteroid

Itokawa would normally be a fairly average near-Earth asteroid – a rocky mass measuring only a few hundred metres in diameter, which orbits the sun amid countless other celestial bodies and repeatedly crosses the orbit of the Earth. But there is one fact that sets Itokawa apart: in 2005 it became a visit from Earth.
