If NASA were to launch an interstellar probe powered by solar sails, it would take only eight years for it to catch the Voyager 1 spacecraft (the most distant spacecraft from Earth), which has been traveling for more than 20 years. By adding a laser or magnetic beam transmitter, NASA sa...
That's why very large objects, such as the planet Jupiter, have a greater gravitational pull than the moon, which is a much smaller heavenly body. Tell children that they weigh more on Earth than they would on the moon because of the differences in gravity of those two objects. Note that...
Their new Voyager 35L model weighs just 2 pounds making it ideal for light hikers looking to travel lightly. It also features their signature Vibram® soles which allow trail users to walk comfortably even when wet. 2. How Much Stuff Will You Be Carrying? This is probably the hardest part...
It takes surprisingly little force to distort the figure of a much thicker Newt primary mirror, yet this does not occur to people who wrist-crunch the retention rings screws of the much thinner corrector of their SCT. Removing strain from the corrector will restore its fine figure and remove ...

So if the Solar System penny is in one endzone of a football field, the nearest star is a pinprick in the other endzone, and Voyager 1, the fastest-moving manmade object, which has been whizzing away from us for 38 straight years, has traveled only 4 cm away from the penny—making...
How Much Wine Can You Bring Back into the USA? Rule 2: when it comes to bringing alcohol into US in checked luggage, you need to adhere to the TSA’s rules on alcoholic beverages. The TSA alcohol limit is divided into two categories: ...
Voyager 1 took photos of Jupiter and two of its satellites (Io, left, and Europa). The new study says that moons orbiting a gas giant planet greater than 8 Jupiter masses could help astronomers detect a rogue planet. (Image credit: NASA/JPL) There may be about 2,800 interstellar planets...
