There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life’s final extinction will occur.
An abundant type of hot ocean exoplanet, despite being decidedly un-Earth-like, could have the right stuff for hosting microbial life.
NASA ’s Roman Space Telescope ’s Coronagraph Instrument, designed to observe distant exoplanets by blocking stellar light, has passed essential tests, marking a significant advancement in space observation technology and the search for extraterrestrial life.
A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027.
The Coronagraph Instrument on NASA’s Nancy Grace Roman Space Telescope will demonstrate new technologies that could vastly increase the number of planets outside our solar system (exoplanets) that scientists can directly observe. Designed and built at the agency’s Jet Propulsion Laboratory in Southern California, it recently passed a series of critical tests ahead of launch. That includes tests to ensure the instrument’s electrical components don’t interfere with those on the rest of the observatory and vice versa.
Science Fiction has long contemplated the idea that alien life not based on carbon chemistry such as silicon might exist on distant and strange worlds, or might be made to exist advanced biological engineering. What would such life be like?

A European Space Agency satellite is expected to reenter and largely burn up in Earth’s atmosphere on Wednesday morning.
The agency’s Space Debris Office, along with an international surveillance network, is monitoring and tracking the Earth-observing ERS-2 satellite, which is predicted to make its reentry at 3:53 p.m. ET Wednesday, with a 7.5-hour window of uncertainty. The ESA is also providing live updates on its website.
“As the spacecraft’s reentry is ‘natural’, without the possibility to perform manoeuvers, it is impossible to know exactly where and when it will reenter the atmosphere and begin to burn up,” according to a statement from the agency.
New research posits that life originated somewhere in the cosmos — and that it traveled through space on tiny particles of cosmic dust.
As we search the heavens for signs of alien life, is it possible that the easiest place to find aliens is to look in the mirror?

Does life appear independently on different planets in the galaxy? Or does it spread from world to world? Or does it do both?
New research shows how life could spread via a basic, simple pathway: cosmic dust.
One thing scientists have learned in the past few decades is that life on Earth might have had an early start.
