This is Herschel’s Garnet Star! 🌟🌟🌟

If Herschel’s Garnet Star and the Sun were placed both at a same distance of 10 parsecs, this star would be 100,000 times brighter than our Sun! It is so big that if it were in the Solar System, it would engulf up to the orbit of Jupiter! ✨✨✨

NASA’s Search for Life: Astrobiology in the Solar System and Beyond

Are we alone in the universe? So far, the only life we know of is right here on Earth. But here at NASA, we’re looking.

We’re exploring the solar system and beyond to help us answer fundamental questions about life beyond our home planet. From studying the habitability of Mars, probing promising “oceans worlds,” such as Titan and Europa, to identifying Earth-size planets around distant stars, our science missions are working together with a goal to find unmistakable signs of life beyond Earth (a field of science called astrobiology).

Dive into the past, present, and future of our search for life in the universe.

Mission Name: The Viking Project

Launch: Viking 1 on August 20, 1975 & Viking 2 on September 9, 1975

Status: Past

Role in the search for life: The Viking Project was our first attempt to search for life on another planet. The mission’s biology experiments revealed unexpected chemical activity in the Martian soil, but provided no clear evidence for the presence of living microorganisms near the landing sites.

Mission Name: Galileo

Launch: October 18, 1989

Status: Past

Role in the search for life: Galileo orbited Jupiter for almost eight years, and made close passes by all its major moons. The spacecraft returned data that continues to shape astrobiology science –– particularly the discovery that Jupiter’s icy moon Europa has evidence of a subsurface ocean with more water than the total amount of liquid water found on Earth.

Mission Name: Kepler and K2

Launch: March 7, 2009

Status: Past

Role in the search for life: Our first planet-hunting mission, the Kepler Space Telescope, paved the way for our search for life in the solar system and beyond. Kepler left a legacy of more than 2,600 exoplanet discoveries, many of which could be promising places for life.

Mission Name: Perseverance Mars Rover

Launch: July 30, 2020

Status: Present

Role in the search for life: Our newest robot astrobiologist is kicking off a new era of exploration on the Red Planet. The rover will search for signs of ancient microbial life, advancing the agency’s quest to explore the past habitability of Mars.

Mission Name: James Webb Space Telescope

Launch: 2021

Status: Future

Role in the search for life: Webb will be the premier space-based observatory of the next decade. Webb observations will be used to study every phase in the history of the universe, including planets and moons in our solar system, and the formation of distant solar systems potentially capable of supporting life on Earth-like exoplanets.

Mission Name: Europa Clipper

Launch: Targeting 2024

Status: Future

Role in the search for life: Europa Clipper will investigate whether Jupiter’s icy moon Europa, with its subsurface ocean, has the capability to support life. Understanding Europa’s habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet.

Mission Name: Dragonfly

Launch: 2027

Status: Future

Role in the search for life: Dragonfly will deliver a rotorcraft to visit Saturn’s largest and richly organic moon, Titan. This revolutionary mission will explore diverse locations to look for prebiotic chemical processes common on both Titan and Earth.
