Placing two small radio telescopes 100 meters apart allows for interferometry, which enhances the overall resolution of the observations. This configuration effectively simulates a larger telescope with a diameter equal to the distance between the two dishes, enabling the detection of finer details in astronomical objects. Additionally, combining data from both telescopes improves sensitivity and signal quality, allowing for more accurate measurements of celestial phenomena.

Why are there telescopes of the very large array arranged so far apart?

The Very Large Array (VLA) telescopes are arranged far apart to enhance their ability to capture high-resolution images of celestial objects. By using an interferometric technique, the separation between the dishes allows them to simulate a much larger telescope, effectively increasing their angular resolution. This configuration enables astronomers to detect finer details in radio emissions from distant galaxies, stars, and other astronomical phenomena. Additionally, varying the distance between the antennas can provide a range of observational capabilities across different spatial frequencies.


How fast is the great rift valley splitting apart?

The Great Rift Valley is splitting apart at a rate of a few millimeters to a few centimeters per year, varying in different regions along the valley. This slow process of divergence is due to tectonic forces pulling the Earth's crust apart.


How do you break apart lumpy table salt?

You can break apart lumpy table salt by placing it in a sealed bag and gently crushing it with a rolling pin or a mallet. This will help to break up the clumps and restore the salt to a finer consistency for easier use in recipes.


What is it called to measure and place rails the proper distance apart?

The process of measuring and placing rails the proper distance apart is called "track gauge." The track gauge ensures that the distance between the rails is consistent, allowing trains to operate safely and efficiently. Standard gauges, such as the commonly used standard gauge of 1,435 mm (4 ft 8 1⁄2 in), are critical for interoperability among different railway systems.


What does a contour interval of 20 meters mean?

A contour interval of 20 meters means that each contour line on the map represents a change in elevation of 20 meters. These contour lines help to visualize the shape and steepness of the terrain. The closer the contour lines are together, the steeper the terrain, while further apart lines indicate a gentler slope.
