According to research published in the journal Earth and Planetary Science Letters, Earth’s oldest rock (which is 4.1 billion years old) has been found in an Apollo 14 sample from the Moon. If confirmed, it’s an amazing discovery.Continue reading Earth’s oldest rock has been found… on the Moon!
When a meteoroid hits Earth, it’s not because the space rock has “fallen out of” its orbit. It’s because its orbit crosses over Earth’s orbit at the exact right (or wrong) moment.Continue reading Meteorites do not fall to Earth
A very inspirational video created by Michael Marantz, titled “Earth: The Pale Blue Dot”, which contains readings from Carl Sagan’s “Pale Blue Dot“.Continue reading Earth: The Pale Blue Dot by Michael Marantz
By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.Continue reading Dinosaurs were already doomed as the frequency of Asteroid Impacts increased 290 million years ago
As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.Continue reading Five space probes leaving the solar system (for now)
The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times in one second.Continue reading Speed of Light – See how torturously slow it is
Our planet is getting warmer, with an increasing pace. This month, there were three bad, very bad news about global warming. According to a study published in Proceedings of the National Academy of Sciences, Antarctica is losing six times more ice mass annually now than 40 years ago. Another study, published in the scientific journal Advances in Atmospheric Sciences concluded that 2018 was the hottest year ever recorded for the Earth’s oceans. And, according to
Scientists from the China National Space Administration (CNSA) has confirmed that the seedlings taken to the far side of the moon with
Margaret Hamilton is not only one of the first software developers, but she also literally created the term “Software Engineering” to describe her work. The code she wrote successfully put humans on the moon for the first time.Continue reading Margaret Hamilton – her code got humans on the moon
