NASA Spacecraft Ready to ‘Touch’ The Sun as it Prepares For Its Closest Approach

On Jan. 19, 2019, just 161 days after its launch from Cape Canaveral Air Force Station in Florida, NASA’s Parker Solar Probe completed its first orbit of the Sun, reaching the point in its orbit farthest from our star, called aphelion. The spacecraft has now begun the second of 24 planned orbits, on track for its second perihelion, or closest approach to the Sun, on April 4, 2019. Parker Solar Probe entered full operational status (known as Phase E) on Jan. 1, with all systems online and operating as designed. The spacecraft has been delivering data from its instruments to...
The Collision that Formed the Moon has Helped to formation of Life on Earth

The Collision that Formed the Moon has Helped to formation of Life on Earth

The process responsible for the formation of the Earth does not imply the existence of key ingredients for life. New research, however, shows how our planet probably has acquired them. Scientists are saying a Mars-sized planet has hit the Earth about 4.4 billion years ago. On the one hand, it served as a “donor” to the important ingredients for life, as its core was rich in sulfur. On the other – it has led to the formation of the Moon, our natural companion. Experiments prove that much of the nitrogen and carbon of the Earth is the result of this...
New NASA Animations Show How Slowly Light Travels Through Space

New NASA Animations Show How Slowly Light Travels Through Space

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second) If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Thanks to the work of Albert Einstein and others, we now understand light speed to be a theoretical limit: light speed — a constant called “c” — is thought to be not achievable by anything with mass. Is the speed of light really constant?Light travels in waves, and, like sound, can be slowed depending on what it is traveling through. Let’s Start A new...
Jupiter is the Oldest Planet in the Solar System

Jupiter is the Oldest Planet in the Solar System

Jupiter is not only the biggest planet in the Solar System. A new study of astronomers from Laurence Livermore’s Californian Laboratory, and the University of Munster in Germany, defines Jupiter as the oldest planet in the solar system, Space.com reports. The new analysis of the Planet calculates that the core of Jupiter was 20 times larger than the Earth only 1 million years after the formation of the Sun. This is a fairly short time because young stars usually throw a lot of energy in their first years, which is enough to blow dust and gas to prevent the formation...
What are Perihelion and Aphelion?

What are Perihelion and Aphelion?

If the sun appears a bit more intense than normal to you this week, you have a keen eye. The Earth has just made its closest approach to our nearest star for the year. The orbital milestone is known as “perihelion,” and it marks the time when the distance between the Earth and the Sun is at its smallest. The event occurs every year in early January, and in 2019 it took place Thursday, Jan. 3 at 12:20 a.m. EST (or at 05:20 GMT, depending on your time zone). On average, the Earth orbits the Sun at a distance of...

See What Impressive Astronomical Phenomena Will be Observed in 2019

The new 2019 arrives with the promise of spectacular events that will make lovers of astronomy to stare to the night sky. The “Meteor showers” Perseid and Geminid invariably present impressive celestial performances, but there will be other astronomical events during the year that are worth watching, according to Gizmodo website. In 2019, lovers of the night sky will witness a total eclipse of the Sun, three partial Solar eclipses, three super Moons – on January 21, February 19 and March 21, complete and partial lunar eclipse, a rare transit (passage) of Mercury in front of the Sun. The rare...
Scientists Want to Change the Definition of Planet

Scientists Want to Change the Definition of Planet

  According to NASA scientists, involved in the New Horizons project, the definition of Planet should be changed. They are ready with a new classification which, if accepted, will add more than 100 new Planets in the Solar System, reported the online edition of Science Alert. Currently as a “Planet” is defined a single cosmic body that orbits the Sun and meets certain orbital criteria. Scientists say this is not correct. “While respecting intelligent scientific classification and people’s intuition, we offer a geographically based definition of a “Planet” that focuses primarily on its physical properties rather than on orbital”, the...
