Visual Magnitude: This is the astronomer's scale for measuring the brightness of objects in the sky. The dimmest object visible in the night sky under perfectly dark conditions is about magnitude 6.5. Brighter stars are magnitude 2 or 1. The brightest objects get negative numbers. Venus can be as bright as magnitude minus 4.9. The full moon is minus 12.7 and the sun is minus 26.8. There are 30 additional discs available when you visit Astrial, Sega Toys' official online store. Simulations of the aurora borealis and the aurora australis are perhaps the highlights. There is a disc that displays the planets of the solar system as well, but it is the ones that show galaxies, nebulas and other NASA-based imagery that really stand out. For example, the North America nebula as taken by NASA's Spitzer Space Telescope and the weird seven-star system called Jabbah (officially called Nu Scorpii and IC 4592) as imaged by NASA's WISE mission. You can also buy disks that simulate fireworks, 'night jellyfish' and a hot-air balloon festival.
As discussed in our Create a Night Sky Projection Kit review, this is a great learning device when assembled with a guardian. The goal is to create a globe-like night sky that shines and projects the constellations. Before moving on to the stars, children learn about the northern and southern hemispheres. Then, they make holes with a sharp tool where the major stars should be, which introduces them to the important stars and constellations in the night sky.In the western sky on Tuesday evening, Nov. 28, the very bright star Vega in the constellation of Lyra the Harp will be descending the western sky. (Image credit: Chris Vaughan/Starry Night) When you are in the city, only a few of the brightest stars are visible. But when you are in the country, you can see many more stars than you can count. Sometimes you can even see the bright belt of our galaxy, the Milky Way. Why is this so? The only thing we didn't like was that it is powered by USB-A to DC cable, which seems a little outdated (we'd prefer USB-C), but aside from that, it would make an excellent gift for any space lover for any occasion. Aurora Borealis Northern Lights Star ProjectorIt's highly customizable, the patterns are realistic and the music rhythm mode is impressive. This is one of our favorites. ★★★★½
Although small and discreet, this USB-powered projector has the capability to turn any room into a celestial wonderland. When connected to a USB power source, it projects hundreds of laser stars, providing a truly immersive and atmospheric experience. Whether you're a gamer aiming to elevate your gaming space, a parent wanting to create a magical bedtime atmosphere for your child (ensuring they don't look directly into the beam) or just someone who enjoys the beauty of the cosmos on a dark and dreary night, this star projector is sure to bring joy. Because stargazing is best done from a dark place away from city lights, dark adaptation is important to achieve and maintain. It takes several minutes for eyes to adjust to the darkness necessary for seeing the most stars, and surroundings on the ground are hard to discern. A red flashlight (torch) can be used to illuminate star charts, telescope parts, and the like without undoing the dark adaptation. (See Purkinje effect). That corresponds to six by two full moon diameters! In a dark sky, M31 can be seen with your unaided eyes as a sizeable faint smudge located 1.4 fist diameters to the lower left (or 14 degrees to the celestial northeast) of Alpheratz, the star that occupies the lower left (northeastern) corner of the Great Square of Pegasus. The three higher (westernmost) stars of Cassiopeia, named Caph, Shedar, and Gamma Cas, also conveniently form an arrow that points toward M31. The U.S Food and Drug Administration (FDA) states that ' The FDA recognizes four major hazard classes (I to IV) of lasers, including three subclasses (IIa, IIIa, and IIIb). The higher the class, the more powerful the laser is and the greater the potential to pose serious injury if used improperly. ' Astronaut Starry Sky Star Projector:A well-made novelty star projector that every kid, or space fan, will love to have in their bedroom. It isn't quite on par with other star projectors performance-wise, but it does everything we'd expect of it, given its reasonable price. ★★★★There are no markings on the night sky, though there exist many sky maps to aid stargazers in identifying constellations and other celestial objects. Constellations are prominent because their stars tend to be brighter than other nearby stars in the sky. Different cultures have created different groupings of constellations based on differing interpretations of the more-or-less random patterns of dots in the sky. Constellations were identified without regard to distance to each star, but instead as if they were all dots on a dome. Bluetooth speakers tend to be quite poor quality, but we thought the speaker was surprisingly high quality and had excellent sound clarity and detail. The adjustable sound settings are a plus, enabling you to customize the sound to your liking and to switch to a different genre of music. With three adjustable ridges on the bottom, you can easily position this projector at three different angles, including upward onto a ceiling. It utilizes both LED and direct laser diode technologies to produce dynamic RGB projections with moving patterns. It's portable and convenient, powered by a USB cable, enabling you to connect it to a computer or a portable battery. On November evenings, the Andromeda Galaxy is positioned very high in the eastern sky. This large spiral galaxy, also designated Messier 31 (or M31) and NGC 224, is located 2.5 million light-years from us, and covers an area of sky measuring 3 by 1 degrees.
The northeastern sky on November evenings hosts the bright constellations of Perseus and W-shaped Cassiopeia, with the very bright star Capella positioned below them. Meteors (commonly known as shooting stars) streak across the sky very infrequently. During a meteor shower, they may average one a minute at irregular intervals, but otherwise their appearance is a random surprise. The occasional meteor will make a bright, fleeting streak across the sky, and they can be very bright in comparison to the night sky. After the first week of November Mercury will become visible above the southwestern horizon after sunset. Its position several degrees south of the ecliptic will hold it very low in the sky for mid-northern latitude observers — making this a very poor apparition for them, but an excellent one for residents of the tropics and the Southern Hemisphere where the planet will be much higher after sunset. Operation is manual rather than digital, but you can access additional informative descriptions of the pictures on the slides online using a provided 'secret code.' This allows children to learn more about the objects in space and adds a bit of fun and mystery to learning.

Scientists believe that the Moon formed early in the solar system’s history after Earth and an object about the size of Mars smashed into each other. The impact sent chunks of Earth and the impactor into space that were pulled together by gravity, creating the Moon.
Neptune's westerly motion will be slowing as it readies to complete its retrograde loop next month. The planet will be easiest to see while it is highest in the sky during early evening. Much brighter Saturn will be shining about 24 degrees to Neptune's lower right (or celestial west). In a telescope, Neptune's tiny apparent disk will span 2.3 arc-seconds, but larger telescopes can also show Neptune's large moon Triton. The bright, waxing gibbous moon will hop past Neptune on Nov. 21-22. Skywatching terms The spherical design means you have near 360-degree angling, and it comes with a 1.5 m cable, giving maximum positioning flexibility. This gives it a slight edge over the Encalife Atmosphere Smart Galaxy Smart Projector, which has similar specs but can only be used in four fixed positions. Bresser Junior Astro-Planetarium DeluxeThis Bresser planetarium star projector, designed for kids, has true-to-life projections, a five-year warranty and is simple to operate. It has a time and date selector, a shooting star function and a sleep timer, and it ships with two disks.★★★½ Create A Night Sky Projection Kit:If you've got time with the kids to fill, this could be a fun introduction to stargazing. Don't expect to be dazzled by a plug-and-play awe-inspiring experience, but you can enjoy the process of setting it up with your kids.★★★ Since Mercury will be reducing its distance from Earth during November, the planet will diminish in brightness from magnitude -0.6 to -0.47, wane in illuminated phase, and grow in apparent disk size in a telescope — ending the month just days away from its greatest eastern elongation and showing a 72%-lit, 6.2 arc-seconds-wide football shape.The sky between Perseus and Cassiopeia hosts the Double Cluster, a pair of bright open star clusters that together cover a finger's width of the sky. They make a spectacular sight in binoculars (orange circle) or a telescope at low magnification. Another source of light that can interfere with star gazing is light from the urban environment, called light pollution. Try a similar experiment using your star counter to see if the number of visible stars changes at different locations with different amounts of light pollution. Is there a difference between a busy street corner and a large open space? How can urban areas diminish the effects of light pollution? The fact that the sky is not completely dark at night, even in the absence of moonlight and city lights, can be easily observed, since if the sky were absolutely dark, one would not be able to see the silhouette of an object against the sky. Brainstorm Toys Deep Space Home Planetarium Star ProjectorA neat little STEM toy with multiple functions. Kids between 6 and 10 will love to learn more about space with this hands-on device.★★★½ Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing. Aurorae light up the skies above the polar circles. Occasionally, a large coronal mass ejection from the Sun or simply high levels of solar wind may extend the phenomenon toward the Equator. [1]
