Orbital resonance − the striking gravitational dance done by planets with aligning orbits
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are like grains of sand in a region...
Scientists find galaxy that shouldn’t exist
In a universe filled with stars and galaxies, a team of space scientists led by Tim Carleton from Arizona State University has stumbled upon...
How could laser-driven lightsails remain stable
It’s a long way to the nearest star, which means conventional rockets won’t get us there. The fuel requirements would make our ship prohibitively...
How dangerous are Kilonovae?
When we look up at the sky on a particularly dark night, there is a sense of timelessness.
We might see the flash of a...
Atmospheres in the TRAPPIST-1 system should be long gone
Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away.
All of the worlds are similar to Earth...
A super-earth (and possible earth-sized) exoplanet found in the habitable zone
Astronomers have found a new Super-Earth orbiting an M-dwarf (red dwarf) star about 137 light-years away.
The planet is named TOI-715b, and it’s about 1.55...
Dark matter might help explain how supermassive black holes can merge
Although the exact nature of dark matter continues to elude astronomers, we have gained some understanding of its general physical properties.
We know how it...
Giant planet puzzles scientists by orbiting a tiny star
In a surprising twist to what scientists thought they knew about space, a team from Penn State University has found a planet that's way...
Asteroid Ryugu contained bonus comet particles
On December 5th, 2020, Japan’s Hayabusa2 mission successfully returned samples it had collected from the Near-Earth Asteroid (NEA) 162173 Ryugu home.
Since asteroids are basically...
Even early galaxies grew hand-in-hand with their supermassive black holes
Within almost every galaxy there is a supermassive black hole.
This by itself implies some kind of formative connection between the two.
We have also observed...
