781-Comet C.2023 V5 (Leonard)

Travelers In The Night ·

2024/01/26

My Catalina Sky Survey teammate Greg Leonard was asteroid hunting in the constellation of Aquarius with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered his 19th comet. Turns out Greg's new comet is a member of a family of comets orbiting the Sun like a string of cosmic pearls across the vast distances in our solar system.

268E-280-Ice Volcanos

Travelers In The Night ·

2024/01/23

Scientists have spotted icy plumes coming from below the surface of Saturn's moon Enceladus but have yet to witness such events on Ceres. Even so there is significant evidence which points to the possibility of a liquid water ocean layer below Ceres icy crust which could provide an environment suitable for microorganisms.

2024/01/19

My Catalina Sky Survey teammate David Rankin was being filmed and interviewed by the NASA 360 crew at our 60 inch telescope on Mt. Lemmon, Arizona when he discovered a scary space rock moving through the constellation of Aquarius at 13 mi/s.Rest assured that asteroid hunters will carefully keep track of 2023 VS3 to make sure that its orbit does not change to make it a threat in the distant future as it passes near to Earth, Mars, and other asteroids.

267E-279-Hottest

Travelers In The Night ·

2024/01/16

The warming that is happening is having a variety of consequences. In the American midwest and northeast extreme heat, heavy rain storms, and flooding will impact agriculture, forestry, infrastructure, and air as well as water quality. In the southwest increased heat, insect outbreaks, and declining water supplies will increase the possibility of wild fires and other threats. Costal regions regions are experiencing sea level rises and storm surges which effect ports, tourism, and the fishing

779-What If An Asteroid is About To Impact Earth?

Travelers In The Night ·

2024/01/12

A research project whoes goal is to explore if it would be possible, on short notice, to pulverize a small asteroid so that it would not enter the Earth’s atmosphere as a single object perhaps saving humanity from an very expensive sonic boom.

Travelers In The Night ·

2024/01/09

This is the story of the big one that got away. It illustrates the problem that there are a number of possible orbits which may fit a short arc of an object in the night sky. There may be scores of kilometer sized objects out there but 2016 NA39 is not one of them.

Matching his wife’s discovery of two comets on the same observing run seven years previously my Catalina Sky Survey team caption Carson Fuls discovered two comets on consecutive nights. They have very different origins and ultimater fates.

265E-277-Old Girl

Travelers In The Night ·

2024/01/02

Imagine a telescope old enough for Senior Citizen discounts, which has traveled between mountains, and started life with a metal mirror measuring one thing at time being equipped with a camera with 100 million pixels. This is the story of the "old girl", the 60 inch Catalina Sky Survey telescope on Mt. Lemmon, Arizona.

Travelers In The Night ·

2023/12/26

During a 6 night observing run with the 60 inch telescope on Mt. Lemmon, Arizona, my Catalina Sky Survey teammate Carson Fuls discovered three new Potentially Hazardous Asteroids. They range in size from 600 to 1500 feet in diameter. Fortunately, none of them comes closer than about 14 times the Moon's distance from us.

776-Naming Asteroids and Comets

Travelers In The Night ·

2023/12/22

Historically explorers in many fields of human endeavor have been granted the privilege to name their discovery. If you find a new comet and it receives enough followup observations it will carry your last name. Every year a significant number of comets and asteroids are discovered by amateur astronomers with modest equipment.Their reward is satisfaction and the right to name their discovery.

263E-275-No Place Like Home

Travelers In The Night ·

2023/12/19

Robotic spacecraft from Earth have been traveling around the solar system for decades. What they have found is that there may be a few places on which the toughest terrestrial life forms could exist but nowhere that you could survive without a space suit. A striking by product of these missions are the photographs of our home planet that these robots have sent back to Earth.

775-3 Close Approaches

Travelers In The Night ·

2023/12/15

During a six hour period three small space rocks passed through the Earth-Moon system. At discovery 2023 TO4 was in Pegasus, 2023 TD7 was in Aries , and 2023 TQ3 was in Eradanus.If 2023 TD7 had been an impactor David’s early discovery would have given some of us a chance to view a spectacular event as well as to provide a place for meteorite hunters to look for fragments. For Travelers in the Night this is Dr. Al Grauer.  Stay Tuned.

262E-274-New Horizons Continues

Travelers In The Night ·

2023/12/12

The NASA New Horizons spacecraft obtained intriguing images and data during it's trip through the Pluto system which will keep planetary scientists busy for years to come. Now the New Horizons has it's sights set on an object, a billion miles past Pluto, which is called 2014 MU69. It is too faint for all but the most powerful telescopes which is why the Hubble Space Telescope was systematically used to discover it.

774-Loss and Gain

Travelers In The Night ·

2023/12/08

The Catalina Sky Survey searchs the sky as rapidly as possible in search of Earth approaching objects that could pose a threat to our home planet. The Vera Rubin Observatory will obtain 200,000 images per year to discover things that move or change brightness down to a very faint magnitude.

261E-273-Hunt for Planet9

Travelers In The Night ·

2023/12/05

Evidence continues to mount that there is an unseen body, Planet 9, orbiting far from our Sun. Ideas of where to look for it are being guided by it's gravitational influence on objects in the distant region of our solar system called the Kuiper Belt.

773- Discovery and Recovery

Travelers In The Night ·

2023/12/01

New observations linked with discovery observations 10 years earlier provide a significant improvement in the precision of our knowledge of 2013 TG6’s orbital elements and thus its position on the sky well into the future.It is important for asteroid hunters to keep track of small asteroids like this one to make sure sure that their path doesn’t change to make them a threat as they pass other objects in space.

On a mountain top in the foothills of the Andes in northern Chile a new kind telescope, the LSST, is under construction. It's unique design allows it to image an area of the sky 40 times the size of the full moon and thus record the entire sky twice a week. In 30 seconds the LSST can spot objects 10 million times fainter than we can see with our eyes. It will discover objects which change in brightness and position to enable astronomers to study dark energy, weird stars, Earth approaching objects,
