MIT astrophysicists looked 163,000 light years from Earth, to find that a tiny, ancient galaxy has a dark matter halo - meaning that the very first galaxies in the universe were more immense than anyone imagined.
The hot outer later of our local star has an unusual chemical composition compared to the inner layers - now, scientists think they have an answer for the mystery of the Sun.
Images from the Hubble Space Telescope are giving astronomers the chance to further investigate planetary nebulae - like the striking Jewel Bug Nebula (NGC 7027).
Researchers are now looking at the crystalline solid form of water from different planets, to understand how planets, satellites and even comets evolved.
In Puerto Rico, the Arecibo observatory has found potential "first hints" of low-frequency gravitational waves - which signal the movement of massive entities, like black holes or neuron stars.
Through a telescope in the Atacama Desert of Chile, an old argument between scientists has been settled - they now agree that our universe is approximately 14 billion years old.
The Harvard-Smithsonian Center for Astrophysics found that growing interest in moon resources could create international tension, as extraction becomes possible.
Dr David Carroll from CU Aerospace LLC says that there are advantages to nano-satellites and the Space 2.0 environment, but they exacerbate the problem of orbital debris.
Future spaceports can apply for a share of £2 million to support plans for small satellite launch from aircraft and sub-orbital flight from the UK: What is next for spaceflight?
A series of breakthroughs in materials science are helping to drive efficiency in aerospace manufacturing, by improving material properties and reducing aircraft production times, whilst maintaining a low overall weight.
Scientists working with the Event Horizon Telescope (EHT) have revealed the fruits of an all-consuming attempt to see the impossible: In 2019, we now have the first-ever image of a black hole.
