Why is naming a star with Name a Star a unique gift idea? Name a star provides the opportunity to name a real star in the sky that currently only has a catalog number. You then customize the gift to honor the recipient on the special occasion. The most popular customization is for you to create a short tribute or message that is printed on the Certificate of Registration. These can be funny, serious, or sad depending on the situation. You can use one of the sample tributes or create your own unique tribute. Let’s look at some of the […]

The names of stars come from many sources that vary in different regions of the world. Many cultures have rich histories of naming stars for mythology, agriculture, timekeeping, and navigation. Some of the most notable ancient cultures to catalog star names are Greek, Egyptian, Chinese, Polynesian, Persian, Indian, Babylonian, and Native American. The Chinese inscribed star names on tortoise shells and were the first to record a super nova. Early Polynesians were highly skilled wayfinders who sailed thousands of miles over open ocean navigating by the stars. Egyptians created the modern calendar to predict the annual flooding of the Nile […]

Lions, meteors, and space dust in the sky. Oh my! Spring is a great time for stargazing. Temperatures have gotten a bit warmer and the nights are still long. In 2021, the spring equinox is officially March 20th. A very bright Venus is still visible on the western horizon just after dark. To the south, Orion’s belt with the brightest star in the sky, Sirius, will disappear below the horizon in a few weeks, so get your last look until next fall. In the east, the stars of spring are rising: Regulus in Leo, ruby red supergiant Arcturus in Boötes, […]

The interstellar space between stars is not empty. It contains large amounts of gas and dust particles. These particles swirl around in space, and just like the dust in your house, they are not evenly distributed. We have all found dust bunnies under the furniture in the corners. The same thing happens in space as these particles accumulate into molecular clouds. Molecular clouds are mix of atoms, molecules, and dust. Atoms are the small building blocks of all the stuff around us. Molecules consist of two or more atoms joined together. The molecules present in molecular clouds are typically molecular […]

The brightest stars which are easily visible by the naked eye were named by many ancient cultures including Greek, Latin, Arabic, Australian Aboriginal, Chinese, Coptic, Hindu, Mayan, Polynesian and South African. As a result many stars have multiple names. Technically, anyone is free to give any name to any star, but if a name for an individual star is going to be used consistently by professional astronomers, it has to be approved by the International Astronomical Union (IAU). The IAU is the only internationally recognized authority for assigning names to celestial objects and surface features on them. So far the IAU has only approved […]

The night sky has inspired romance, wonder, and art for thousands of years. Check out the story of Cepheus and Cassiopeia. He was the easy going king of Ethiopia and she was the vain queen, a “mirror, mirror on the wall” type. Poseidon sent a sea monster after Cassiopeia for insulting his wife. She survived that ordeal, only to then insult Hera, queen of the Greek gods. Hera dispatched Cassiopeia to the sky.  A heart broken Cepheus begged his buddy Zeus to send him to be with his beloved Cassiopeia. Now Cephus and Cassiopea permanently embrace in the heavens. How […]

Bright stars top Christmas trees in homes around much of the world. The Star of Bethlehem or Christmas Star has appeared in art, literature, and science for over 2,000 years, but where is it and how can you see it? The Star of Bethlehem is part of the nativity story in the Gospel of Matthew. Three “wise men from the East” (Magi) are inspired to follow the star to Bethlehem to bring gifts to the baby Jesus. The star moved across the sky, then stopped over a manger marking the location for the birth of Jesus. This is the only mention […]

How old are the stars? The short answer is “It’s complicated”, but we can have some fun with this question. For example did you know that there is a star that is older than the universe? That is right. Scientists estimate the age of the universe at 13.8 billion years, but they also believe there is a star that is 14.2 billion years old. This discrepancy is referred to as the “age paradox” and it pits cosmologists against astrophysicists. Now isn’t that fun? Cosmologists measured cosmic microwave background radiation to derive the expansion rate of the universe. The expansion rate […]

Even though it is cold, Winter can be the best time of year for stargazing, because low humidity brings clear skies. The sun goes down early too, so it gets plenty dark to take the kids out before bed time. Bundle up and go outside to see some of the brightest stars and popular constellations. Let Orion be your guide to the winter night sky. The belt points to some of the brightest stars in the sky and Orion’s sword contains one of the best known and most photographed nebulae in the sky, the Orion Nebula (Messier 42). Follow the line formed […]
