Utah Skies: Viewing Mercury In May

May 6, 2021
Dell Vance

On May 4, just after sundown, Mercury will be just above the West-Northwest horizon. It will be a very bright Magnitude of -0.8. Just a couple of degrees north of Mercury, the Pleiades (also known as the Seven Sisters) will be dim, but visible. The Pleiades will be easier to see with binoculars. As the month proceeds, Venus will be joining Mercury in the early evening sky. They will be closest on May 17.

This last week of April will bring a couple of astronomical events that will be worth watching. The first of these will be the Lyrid Meteor Shower.  This will happen from April 16 to the 25, with the peak of the shower activity happening from April 22 to the 23.  The Lyrids is one of the oldest meteor showers and is named after the constellation Lyra.  Look to the east for the bright star Vega to have the best possible viewing during this week.

Utah Skies: Moons Of Our Solar System

April 7, 2021, just before sunrise, Saturn, Jupiter, and a crescent Moon will be visible in the east southeast. The highest bright object is Saturn. Saturn has 82 known moons. Saturn has the most moons in the Solar System. Titan, the second largest moon in the Solar System, is Saturn’s largest moon. It is usually far enough away from Saturn that it is easy to see in most telescopes. In larger telescopes you may even see the smaller moon Rhea.

The Milky Way Galaxy is a spiral galaxy with several arms. Our solar system is located in one of the smaller arms, the Orion Arm. In the wintertime evening sky, the Milky Way runs from Cassiopeia to a position just east of Orion. The Milky Way can be easily found by locating Sirius, the Dog Star, and Procyon. The Orion Arm of the Milky Way lies between these two stars.

Utah Skies: Telescopes And The Future

Feb 24, 2021
Bruce Horrocks

In the summer of 1968, my father and I went to a neighbor’s house to look through a new telescope he had just purchased. I was eight-years-old and with the United States in the heat of the space race, I was fascinated with both rockets and telescopes. I remember that night looking though this new telescope and seeing the planet Saturn with it rings for the first time in my life. I was hooked, and I knew right then what I wanted for Christmas that year and thankfully Santa placed a new Sears telescope under the tree for me and my father to enjoy for many years to come.

Utah Skies: Perseverance Lands On Mars

Feb 23, 2021
NASA

About every two years Earth and Mars are aligned in their orbits so that a space mission can be sent to Mars at the most opportune time. That alignment took place during July 2020 when NASA launched the large robotic rover called Perseverance to Mars. After a 300 million  mile journey, Perseverance landed on Mars on Feb. 18. Another Mars adventure begins on the Red Planet.

Utah Skies: Clyde Tombaugh and Pluto

Feb 23, 2021
Dell Vance

Clyde Tombaugh, as a young man, built his own Telescopes and made sketches of Mars and Jupiter. In 1929 he sent his sketches to the Lowell Observatory in Flagstaff, Arizona. The staff was impressed with his work and offered him a job as a researcher on a project to find Planet X.

Utah Skies: Proxima Centauri Radio Waves?

Feb 13, 2021
NASA Hubble Space Telescope

Over the last twenty years or so, astronomers have detected over 4,000 planets orbiting other star systems. Our Milky Way galaxy may have billions of planets orbiting other stars. It’s a goal to find earth-sized planets orbiting their stars in what is called the habitable zone, or that distance from their parent star where any water on the planet is liquid. 

Utah Skies: Three Mars Missions In February

NASA/JPT/Cal Tech

Mars has been the center for the search for life in our solar system since the first US Viking lander in 1976. Since that time dozens of unmanned missions have been sent to Mars by the US or Russia as orbiters, landers or rovers.

Utah Skies: Orion

Jan 26, 2021

The constellation Orion is certainly one of the most recognized objects in the winter sky. In the middle star that forms the sword of Orion, we find the mighty Orion Nebula. Charles Messier included this in his catalog of deep space objects, and it is known as M42.

Utah Skies: The Moon, Mars, Uranus

Utah Skies: Orion In January

Jan 13, 2021
Stellarium App

Orion is one of the brightest constellations in the January skies. It represents a famous hunter who often bragged about his hunting prowess. Mother Earth became concerned about Orion’s destroying all the predators so she placed a giant scorpion with heavy armor for protection near Orion. The giant scorpion was able to sting Orion causing his death. The gods immortalized Orion and placed him among the stars. The scorpion was also placed among the stars, but only to be seen six months later in summer skies. 

Utah Skies: The Great Conjunction of 2020

Dec 22, 2020
NASA/JPL-Caltech

In astronomy a conjunction is when two or more planets come very close to each other in the sky because their orbits line up with the Earth’s orbit. On December 21, we will be treated with not only a conjunction of two planets, but a great conjunction. Just after the sun sets the planets Jupiter and Saturn will appear so close to each other they will appear to the human eye to be one bright planet.

Utah Skies: The Geminid Meteor Shower

The best meteor shower of the year will occur this week on Sunday evening. Up to 120 meteors per hour may be observed. The Geminid meteor shower is known to have some fireballs that are much brighter than the average meteor and leave long trails that linger in the sky.

Utah Skies: Kepler 1649 c

Dec 2, 2020
By NASA/Ames Research Center/Daniel Rutter

Just a little over 300 light years from Earth in the constellation of Cygnus, astronomers have discovered a rocky exoplanet that is very similar in size to the Earth, orbiting a star in what is called the habitable zone. This means that the planet is in a place where it is not too cold or too hot, and where the conditions are favorable for the existence of life. To be clear however, life has not yet been found on this planet.

Utah Skies: November Penumbral Eclipse

Nov 25, 2020
Stellarium Planetary App

Mark your calendar for the evening of November 30th. On that evening you will see the November full moon called the Beaver moon or the Frost moon. You can find the moon located in the constellations of Taurus the Bull and Aries the Ram.

The International Space Station is a permanently crewed Earth orbiting station. Over 230 astronauts, cosmonauts and other space visitors from 19 nations have visited the space station.

Utah Skies: Apophis, A Large Near Earth Object

Nov 17, 2020
Astronomical Institute of the Charles University: Josef Ďurech, Vojtěch Sidorin

On April 13, 2029 a large asteroid named Apophis (Op-O-Hiss) with a diameter of over 1,000 feet will pass within 19,000 miles of the Earth. Because this asteroid is so large and comes so close to earth it could possibly be observed with the naked eye by about 2 billion people as it moves across the sky. This is the largest known asteroid to come this close to Earth in our life time. This event is still nine years away giving scientists time to plan how to observe it and learn what they can from this rare event.

Utah Skies: Fomalhaut, The Lonely Star of Autumn

Nov 10, 2020
NASA and ESA

Fomalhaut at this time of year can be seen as a bright star in the southern sky. Fomalhaut is also called the Lonely Star of Autumn because it is the only bright star in the evening sky at this time of year.

Utah Skies: Mars At Opposition

Oct 16, 2020
Celestron Sky Portal App

On Oct. 6,  the planet Mars was nearer the Earth than at any time since July 2018. It will not be this close again for another 16 years. If you own a telescope this would be a good time to take a look. You may be able to observe some markings on its surface and an icecap on its pole.
