The smallest galaxies in our universe bring more about dark matter to light
A team of researchers has investigated the strength of dark matter scattered across the smallest galaxies in the universe using stellar kinematics. They discovered that the strength of dark matter is quite small, suggesting that dark matter does not easily scatter together.

Mars: Perseverance rover set for nail-biting landing - here's the rocket science
Following 'seven minutes of terror' after it reaches Mars' upper atmosphere, NASA's Perseverance rover is expected to land on the surface of the red planet at 20:55 GMT on February 18. This is incredibly hard to do, with only about 40% of missions succeeding.

Hubble uncovers concentration of small black holes
Astronomers found something they weren't expecting at the heart of the globular cluster NGC 6397: a concentration of smaller black holes lurking there instead of one massive black hole.

Ceramic chips inside meteorites hint at wild days of the early solar system
A new analysis of ceramic chips embedded in meteorites suggests the formation of our solar system was not as quiet and orderly as we once thought.

Astronomers confirm orbit of most distant object ever observed in our solar system
Astronomers have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object observed in our solar system. The planetoid, which has been nicknamed 'Farfarout', was first detected in 2018, and the team has now collected enough observations to pin down its orbit.

Astronomers offer possible explanation for elusive dark-matter-free galaxies
A study has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past.

Study of supergiant star Betelgeuse unveils the cause of its pulsations
Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020, which has prompted speculation that Betelgeuse may be about to explode.

Astronomers spot bizarre, never-before-seen activity from one of the strongest magnets in the Universe
Astronomers have just observed bizarre, never-seen-before behaviour from a 'radio-loud' magnetar - a rare type of neutron star and one of the strongest magnets in the Universe. Their new findings suggest magnetars have more complex magnetic fields than previously thought - which may challenge theories of how they are born and evolve over time.

SpaceX vs NASA: who will get us to the Moon first? Here's how their latest rockets compare
To enable flights to the Moon and beyond, both NASA and SpaceX are developing new heavy lift rockets: SpaceX's Starship and NASA's Space Launch System. But how do they differ and which one is more powerful?

New concept for rocket thruster exploits the mechanism behind solar flares
A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist. The device would apply magnetic fields to cause particles of plasma to shoot out the back of a rocket and propel the craft forward.
