When studying planets or other objects in space scientists can use?

NASA scientists often use a technique called “remote sensing” to study the composition of different elements and structures on planets. Remote sensing refers to making measurements without directly touching the object being measured. These images are one kind of remote-sensing measurement.

What is an example of a space probe?

Examples of each type of space probe include Voyager 2 (interplanetary), Magellan (orbiter), and Pathfinder (lander).

Is the Next Ice Age Coming?

Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years. They go on to predict that emissions have been so high that it will not.
