Telescopes

The collision theory was developed by Max Trautz and William Lewis in the early 20th century. They proposed that chemical reactions occur when reactant molecules collide with sufficient energy and proper orientation. This theory laid the foundation for understanding reaction rates and kinetics in chemistry.

The Hubble Space Telescope is placed in orbit around Earth at an altitude of about 547 kilometers (340 miles) to ensure that it can observe distant celestial objects with minimal interference from Earth's atmosphere. Being above the atmosphere also provides a clearer view of the universe and reduces distortion and light pollution that could affect its observations.

Yes, optical telescopes are specifically designed to study visible light radiated from stars. They collect and focus visible light from stars to provide detailed images and spectra, allowing astronomers to analyze the properties of stars such as temperature, composition, and motion.

Perhaps the most important contribution of radio astronomy to the Big Bang theory was to finally put to rest its only real rival, the Steady State theory.

Steady State theory required the Universe to be eternally similar to the way it is today, with the known expansion of the Universe compensated for by a continual creation of matter in intergalactic space.

However, in 1965, Arno Penzias and Robert Wilson, working with a Bell Labs horn antenna at Holmdel, New Jersey, (and looking for quite something else entirely) discovered a uniform microwave hiss coming from all over the sky. This turned out to match a prediction by George Gamow and others that the Big Bang should leave just such a remnant noise filling the Universe.

The Steady State theory had no explanation for the existence of this noise (now termed the cosmic microwave background), while the Big Bang theory not only demanded it but rather closely predicted its temperature.

The Hubble Telescope is hit by small objects like tiny meteoroids a few times a year, but its robust design and protective shielding help minimize damage. The telescope orbits Earth in a region with relatively low debris density, reducing the likelihood of collisions.

Radio telescopes can detect radio waves from celestial objects billions of light-years away, allowing scientists to observe phenomena such as quasars, pulsars, and the cosmic microwave background radiation. The distance at which a radio telescope can "see" depends on the strength of the signal emitted by the object being observed and the sensitivity of the telescope's receivers.

Solar arrays are a good choice to power the Hubble Space Telescope because they can provide a reliable source of energy in space where sunlight is readily available. They are efficient, lightweight, and require minimal maintenance, making them ideal for long-term space missions like the Hubble. Additionally, solar arrays help to reduce the reliance on battery power and can extend the operational lifetime of the telescope.

Radio telescopes are often placed in valleys because the surrounding hills and mountains shield them from radio interference generated by human activities. Valleys provide a natural barrier that helps to block out unwanted signals and enhance the sensitivity of the telescopes to detect faint radio signals from space. Additionally, valleys can also help to reduce the impact of wind and atmospheric disturbances on the telescopes, leading to clearer observations.

The invention of the telescope is generally attributed to Hans Lippershey in 1608. The first practical telescopes were developed by Galileo Galilei in 1609. So, telescopes have been around for over 400 years.

It is not sure yet. But NASA has predicted the date to be as between 2014 and 2015.

The astronomer whose treatise was named 'Panchasiddhantika' was Varahamihira, an ancient Indian mathematician and astronomer who made significant contributions to the field of astronomy.

It takes a year for the planets to circle around the sun because of their gravitational pull and the sun's size and mass. The time it takes for a planet to orbit the sun is determined by its distance from the sun and its orbital speed. These factors combined result in a year-long orbital period for each planet.

You can see Venus in the evening sky just after sunset and Saturn in the early morning sky just before sunrise. The visibility of planets depends on their position relative to the Sun, so the best times to see them without a telescope change throughout the year.

Optical telescopes are used to study electromagnetic energy in the form of visible light. This allows astronomers to observe and study objects in the universe, such as stars, planets, galaxies, and other celestial bodies that emit or reflect visible light.

Telescopes typically use convex lenses (also called objective lenses) to gather and focus light from distant objects. These lenses help magnify the images and make distant objects appear closer and more detailed. Eyepieces with different magnifications are then used to further enhance the view.

When we observe stars through a telescope, we are seeing light that has traveled vast distances to reach us. Since light takes time to travel these distances, we are essentially seeing the star as it was in the past. For example, if a star is located 1000 light-years away, we are observing light that left the star 1000 years ago, so we are seeing the star as it was 1000 years ago.

Astronomical telescopes have big apertures to collect more light from distant objects in space. Larger apertures allow telescopes to gather more photons, resulting in brighter and more detailed images of celestial objects. This helps astronomers see fainter objects, study them in more detail, and gather more information about the universe.

To observe Mars' rotation using a telescope, you would need to locate the planet in the night sky and track its position over several nights. By observing specific surface features or markings on Mars, such as its polar ice caps or dark surface patches, you can track its rotation period which is roughly 24.6 hours. Note that Mars rotates in the same direction as Earth, so you would need to observe at the same time each night to see the same features.

Answer #2: Unfortunately, JWST's launch date has been pushed back many times (Which isn't always a bad thing!). It's current tentative deployment date is sometime in 2018.

Not yet! It's still being built! The very soonest it would launch is 2014. And after it is launched, it will take another 6 months for the telescope to be deployed, to cool down to its operating temperature, and for its systems to be checked out and adjusted.

A space telescope produces clearer images because it is above Earth's atmosphere, which can distort and blur light from space. By being in space, the telescope eliminates the atmospheric turbulence that can affect the quality of images produced by Earth-based telescopes. This allows space telescopes to capture sharper and more detailed images of celestial objects.

A telescope diaphragm is used to control the amount of light entering the telescope. By adjusting the size of the diaphragm, astronomers can regulate the brightness and contrast of the observed objects, improving visibility and clarity.

Both reflecting telescopes and microscopes use mirrors to focus light instead of lenses. They both have an objective mirror that collects and reflects light to form an image. The primary function of both instruments is to magnify and produce clear images of distant or small objects.

An LED reflector is a type of lighting fixture that contains light emitting diodes (LEDs) and a reflective surface to direct and enhance the light output. They are commonly used in outdoor lighting applications, such as sports fields, parking lots, and architectural lighting, due to their energy efficiency and long lifespan.

Scientist investigate the early universe by observing objects that are extremely far away in space.Beause it takes time for light to travel through space,looking through a telescope is like looking back in time one travels. Looking at distant galaxies evolve through time and perhaps what caused them to form in the first place.Scientiiist have already found some very strange looking objects in the Early universe.
