Most trees can be easily identified by inspecting their leaves, seed pods, flowers, bark, or shape.

At the time of the announcement in January, the asteroid’s impact probability was reported to exceed 1%. The impact probability describes how likely a hazardous asteroid is to hit Earth.

I was preparing for my early morning class back in January 2025 when I received a notice regarding an asteroid called 2024 YR4. It said the probability it could hit Earth was unusually high. As ...

Impact probability To see whether an approaching object could hit Earth, researchers find out what an asteroid’s orbit looks like using a technique called astrometry.

When scientists spot an asteroid whose trajectory might take it close to Earth, they monitor it frequently and calculate the probability that it might collide with our planet.

A t-distribution is a type of probability function that is used for estimating population parameters for small sample sizes or unknown variances.

How to plant balled, burlapped trees For a container-grown tree, you’ll want to gently tap the container off the root ball so you can inspect the roots.
