Hunting Aliens: NASA's Exoplanet Quest


In NASA's quest for knowledge beyond our solar system, the search for exoplanets, or alien worlds, has emerged as a prominent focus.

Kepler Space

NASA's Kepler Space Telescope revolutionized exoplanet discovery, identifying thousands of potential exoplanets by monitoring the tiny dips in brightness as they pass.

TESS Mission

The Transiting Exoplanet Survey Satellite (TESS) continues Kepler's legacy, scanning the skies for exoplanets orbiting bright, nearby stars, expanding our catalog of potential.

James Webb Space

Set to launch soon, the James Webb Space Telescope promises to delve even deeper into the mysteries of exoplanets, with its advanced instruments.


NASA's Exoplanet Exploration Program investigates the potential habitability of exoplanets, assessing factors such as distance from their star, composition.

Similarity Index

Scientists utilize metrics like the Earth Similarity Index to evaluate exoplanets' similarity to Earth, providing insights into their potential to harbor life as we know it.


NASA researchers study biosignatures – indicators of life – in exoplanet atmospheres, employing sophisticated techniques to detect the presence of molecules associated with biological.


NASA engages the public through citizen science initiatives, enlisting volunteers to help analyze data and identify potential exoplanet candidates, fostering a collaborative approach.

Search Continues

As NASA's exoplanet quest continues to unfold, each discovery brings us closer to answering one of humanity's most profound questions: Are we alone in the universe?
