Automated Telescope Finds New Worlds

Nariene

Explore the future of exoplanet discovery with the **Automated Planet Finder (APF)**! Located at Lick Observatory on Mount Hamilton, this pioneering 2.4-meter **robotic telescope** is revolutionizing the search for **potentially habitable exoplanets**. Operational since 2014, the **APF** autonomously determines the orbits and masses of distant worlds.  Discover how the **APF** operates independently each night, scrutinizing up to 25 stars within 100 light-years of Earth using high-precision **radial velocity measurements**. Learn about its unique ability to detect the subtle **gravitational tugs** planets exert on their stars.  While early findings include systems like HD 141399 (four gas giants) and GJ 687 (Neptune-mass planet orbiting a red dwarf star), scientists anticipate many more groundbreaking **exoplanet discoveries**. Beyond its primary mission, the **APF** also contributes to other crucial **astronomical observations**, monitoring supernova explosions and identifying gamma-ray burst sources.  See how the **APF** complements space-based missions like NASA's **Kepler Space Observatory** in expanding humanity's inventory of **exoplanets**, and what the **James Webb Space Telescope** will mean for future discoveries.

00:00The Automated Planet Finder, APF, a 2.4-meter robotic telescope located at Lick Observatory

00:10on California's Mount Hamilton, is a pioneering instrument dedicated to the autonomous search

00:15for potentially habitable exoplanets. Operational since January 2014, the APF has already begun to

00:23yield significant results, precisely determining the orbits and masses of exoplanets that could

00:29potentially support life. Unlike traditional ground-based telescopes that require constant

00:35human supervision for such intricate detection tasks, the APF operates independently. Each night,

00:42its sophisticated algorithm assesses weather conditions and prioritizes observations.

00:48The telescope is programmed to scrutinize up to 25 stars nightly, primarily focusing on those within

00:54approximately 100 light-years of Earth. Its core method involves high-precision radial velocity

01:00measurements, detecting the subtle gravitational tugs exerted on stars by orbiting planets.

01:06While its initial discoveries, which include two previously suspected planetary systems,

01:12demonstrate its capabilities, they are not considered groundbreaking in themselves.

01:17These early findings include HD141399, a system comprising four gas giant planets, and GJ687,

01:27which features a Neptune-mass planet orbiting a red dwarf star. Nevertheless, scientists anticipate that

01:33the APF will uncover many more surprising findings in the future. Beyond its primary role in exoplanet

01:40detection, the APF also serves as a valuable tool for other spectroscopic astronomical observations.

01:47These include monitoring the intense light from supernova explosions and identifying the optical sources of

01:53powerful, sporadic gamma-ray bursts. In the broader context of exoplanet discovery, the APF complements

02:01space-based missions such as NASA's Kepler Space Observatory. Kepler, specifically launched to identify

02:08exoplanets, has already catalogued 715 new planets orbiting 305 stars. Looking ahead, it was anticipated that the

02:18launch of the James Webb Space Telescope, originally projected for 2018, would significantly expand humanity's

02:26understanding and inventory of exoplanets.
