Bringing the Visible Universe into Focus with Robo-AO
Published on: February 12, 2013
Summary
Small telescopes can remain valuable by adapting to specialized, long-term sky monitoring projects. Robotic networks of smaller instruments offer unique survey capabilities complementary to large observatories.
Area of Science:
- Astronomy and Astrophysics
- Observational Astronomy
Background:
- The trend of decommissioning smaller telescopes to fund larger ones is a concern for many astronomers.
- Smaller instruments face obsolescence despite their unique observational potential.
Purpose of the Study:
- To explore how small telescopes (aperture ≤ 2 meters) can maintain relevance in modern astronomy.
- To highlight the potential of adapting small telescopes for specialized survey projects.
Main Methods:
- Focusing on the unique capabilities of small telescopes for wide-field sky monitoring.
- Developing robotic networks of small telescopes for continuous observation.
- Utilizing small telescopes for long-term, repetitive observation of celestial objects.
Main Results:
- Small telescopes are being repurposed into automated, globally distributed networks.
- These networks are effectively undertaking large-scale sky survey projects.
- Such projects are often unfeasible for large, single-aperture telescopes.
Conclusions:
- Small telescopes can thrive by specializing in survey astronomy and robotic operation.
- Repurposed small telescopes offer a cost-effective and unique scientific return.
- The strategic adaptation of small telescope technology ensures their continued contribution to astronomical research.

01:18Imaging Biological Samples with Optical Microscopy
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:22Overview of Microscopy Techniques
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...
01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
01:29Kepler's Second Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.
