In the future one can envision a space mining family boarding a descendent of the SpaceX Falcon Heavy Launch Vehicle for a trip into low Earth orbit. A few hundred miles above the Earth's surface they would rendezvous with their asteroid mining spacecraft which will be their home for the next five years or so.
You can spot Europa with almost any small telescope as a moving point of light orbiting the planet Jupiter just like Galileo Galilei did 400 years ago. Of the 4 moons which you will see Europa is the one second closest to Jupiter.
On December 25, 2017, while searching for Earth approaching asteroids in the constellation of Virgo, the Universe gave my Catalina Sky Survey teammate Greg Leonard a Christmas present in the form of a comet which now bears his name.
Since the dawn of our race, it is likely that humans have looked into the night sky and wondered if they are alone in the Universe on a unique planet. The NASA Kepler spacecraft has discovered more than a thousand planets orbiting distant stars. A newly discovered planet, Kepler-452b has spent 6 billion years in the habitable zone of its star. In the 4.5 billion years of the Earth's history the parade of more than 5 billion species has included single cell organisms, various multi cellular life ...
Recent scientific studies have begun to shed light on the interesting mystery of how the small number of what we now call electrophonic meteors produce simultaneous light and sound. If you are lucky you could hear a meteor's dying whispers and could even be the first person to record these sounds on your cell phone.
The one thousand six hundred and second potentially hazardous asteroid was discovered by the Pan-STARRS group in Hawaii. Followup observations were made by telescopes in Hawaii, France, Australia, Italy, Germany, and Pennsylvania. The Minor Planet Center used these vital observations to calculate an orbit and gave it the name 2015 OC22.
Long Winter nights with good seeing, from start to finish, are those on which the asteroid hunter makes new discoveries while being treated to views of millions of stars, gas clouds, and galaxies which inspire a child like sense of wonder.
At the few remaining natural night sky viewing locations on Earth the horizon has a faint glow in every direction. Near the magnetic poles, this night glow appears to join with the relatively bright higher altitude aurora which covers larger portions of the sky and exhibits beautiful colors including green and red. Green light is the strongest component of the Earth' airglow and comes from oxygen atoms which have become energized by our Sun.
When we find a planet which appears to have the chemical signs of living organisms in its atmosphere, the desire to take a close up look at it will be hard to contain. Laser propelled ultra light space probes could be sent to explore nearby worlds. The cost of investigating our planetary life hosting neighbors is likely to be less than what the US is planning to spend upgrading its nuclear weapons.
After 9 years, 3 billion miles, and 18 sleeping periods NASA gave a wake up call to the New Horizons when it was 135 million miles from the Pluto system. After more than 8 hours of waiting, NASA engineers were ecstatic to receive a message from the New Horizons stating that "I am fine and ready to go forward with an encounter with Pluto".
When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life.
Confronted with the deluge of new possible planets, in 2006, The International Astronomical Union voted to categorize Pluto as a Dwarf Planet and not the 9th planet in our solar system as most school children had learned.
Intriguing features which change with the Martian seasons mimic flows of liquid water on the Earth's surface.
In 1933 Fritz Zwicky suggested that the high speeds of galaxies in the relatively distant Coma Cluster are indicative of some type of invisible material which is pulling on them. In the 1970's Dr. Vera Rubin began to measure the speeds of stars in galaxies using the Doppler shift. She expected stars orbiting at different distances from the centers of spiral galaxies to behave like the planets in our solar system since for these giant star systems the luminous mass that we observe is concentrated...
The first alien object to observed visiting our solar system arrives from truly deep space and leaves us with the mystery of what it is and how it got that way.
Being night sky friendly means that you only use outdoor lighting fixtures which direct light onto the ground where humans need it and not up into the sky where it obscures the natural wonders of the Universe. Currently more than 2/3 of the US population and more than 1/2 of the those people living in Europe cannot see the Milky Way or a meteor streaking through the night sky because of inappropriate outdoor lighting. Amazingly enough being night sky friendly saves money and is good for business...
Earth like planets are being discovered circling the most common type of star in our neighborhood of the Milky Way galaxy.
Did you know that asteroids can bring diamonds to Earth and that asteroids sometimes create diamonds when they collide with our planet?
A small asteroid soars into the lonely space high above and below the plane of our solar system.
About 35 million years ago the Earth was impacted by two large asteroids creating the more than 50 mile diameter Popigai [pop a gay i] Crater in Russia and a similar crater in Chesapeake Bay in the USA. Analysis of fragments indicate that the impacting objects were not made of the same material. This finding has led scientists to speculate that there may be an astronomical process which changes conditions in the inner asteroid belt and causes the Earth's orbit to change slightly. This combinatio...
Perhaps the reason that we have not detected alien civilizations on distant worlds is because they exist in oceans covered by miles of radiation absorbing ice and rocks.
In February 2013 a space rock about 59 feet in diameter entered the Earth's atmosphere over Chelyabinsk, Russia making a fire ball 30 times brighter than our Sun. It came without warning and nearly 1,500 people were injured primarily by flying glass from broken windows. In the end spending a billion dollars a year on asteroid damage prevention is like purchasing expensive insurance for an extremely unlikely event. However, it has a side benefit that it will employ people and may stimulate scienc...
A rock from another solar system is likely to have streaked by Earth before heading back into interstellar space.
There are more than 20,000 pieces of space junk larger than 4 inches in diameter and millions of tiny ones in orbit around the Earth. At orbital speed a flake of paint carries as much energy as a 550 pound object traveling at 60 miles per hour. Eventually all of this stuff will fall back to Earth. So far no injuries or property damage has been confirmed. Heads up.
On it's gravitational leash, Earth's pet space rock, 2016 HO3, accompanies us at a distance of between 38 and 100 times the Moon's distance from Earth as we both travel about the Sun.
For 43 years after its discovery in 1949, the Earth approaching asteroid Icarus, was known as the object which passes closest to our Sun. It is named for a boy in Greek mythology whose wings of feathers and wax melted when he ignored his father's advice and flew too close to the Sun.
To survive on Venus where the temperature is 864F and the surface air pressure is 90 times that of Earth, NASA and JPL engineers are exploring the concept of avoiding the use of modern temperature sensitive electronics by creating a fully mechanical rover.
Using the long arm of the internet, astronomers in Russia are observing with a telescope located near Mayhill, New Mexico to discover solar system objects. The New Mexico Skies Observatory, near the village of Mayhill, is located 7,300 feet above sea level and has world class, clear dark skies, ideal for astronomical viewing. In addition to discovering new objects the ISON-NM telescope is being used to determine the size and shape of asteroids by carefully measuring the light they reflect as the...
What at first appeared to be an asteroid turned out to be a double comet.
Juno was found by German astronomer Karl L. Harding in 1804 who noticed that to the human eye it appeared to be a star like moving point of light in the night sky. The light that Juno reflects suggests that it could be the source of stony meteorites called chondrites that we find on Earth.
