Different methods of searching for and finding distant exoplanets give different information about the planets found.
The transit method — where an exoplanets passed in front of its sun and dims the bright sunlight ever so slightly — gives astronomers not only a detection but also its radius or size.
The radial velocity method — where an exoplanet’s gravity causes its host star to “wobble” in a way that can be measured — provides different information about mass and orbit.
Scientists have discovered the most distant radio blast ever known.
The blast came from a quasar that is so far away that its light took 13 billion years to arrive at Earth.
That means that the signals detected by scientists are coming from a time when the universe was just 780 million years old.
Astronomers have detected the best place and time to live in the Milky Way, in a recent study published in the journal Astronomy and Astrophysics.
More than six billion years ago, the outskirts of the Milky Way were the safest places for the development of possible life forms, sheltered from the most violent explosions in the universe, that is, the gamma-ray bursts and supernovae.

Free conference covering the upcoming MOON ELEVATOR project: 9–11 March. Bringing together government, military, private industry, academia and others, this three day event is sure to be an eye opener on where we are and where we are going in the coming 5–10 years. Don’t miss out! Get your tickets free today.
- Gravitational Elevators (Lunar Space Elevator Infrastructure)
- Centripetal Elevators (Space Elevators from Earth).
We’ll look at both through the lens of.
1) hardware, 2) business, 3) outreach, and 4) framework.
Work is due to start on the world’s first ‘space hotel’ in low Earth orbit in 2025 — and it will come equipped with restaurants, a cinema, spa and…
Developed by the Orbital Assembly Corporation (OAC), the Voyager Station could be operational as early as 2027, with the infrastructure built in orbit around the Earth.
The space station will be a large circle and rotate to generate artificial gravity that will be set at a similar level to the gravity found on the surface of the Moon.
Voyager Station’s hotel will include many of the features you might expect from a cruise ship, including themed restaurants, a health spa and a cinema.
The Spiral of the Southern Pinwheel The Dark Energy Camera (DECam), which was originally designed for the Dark Energy Survey, has captured one of the deepest images ever taken of Messier 83, a spiral galaxy playfully known as the Southern Pinwheel. Built by the US Department of Energy, DECam is mounted on the Víctor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab.
