The only downside with the Atmosphere Smart Galaxy Projector is that the nebulas and stars aren't scientifically accurate. Still, we enjoyed the experience so much that we didn't feel short-changed. We were especially happy with the option to adjust both the brightness and the projection speed, which makes it great for setting a calm environment to relax in, or an energetic party scene.Considering its reasonable price tag and the many educational benefits it offers, we think this projector is a worthwhile investment for homeschooling or simply learning about space with your child.

Robberto, M.; etal. (2005). "An overview of the HST Treasury Program on the Orion Nebula". Bulletin of the American Astronomical Society. 37: 1404. Bibcode: 2005AAS...20714601R. See also see the NASA press release. In 1993, the Hubble Space Telescope first observed the Orion Nebula. Since then, the nebula has been a frequent target for HST studies. The images have been used to build a detailed model of the nebula in three dimensions. Protoplanetary disks have been observed around most of the newly formed stars in the nebula, and the destructive effects of high levels of ultraviolet energy from the most massive stars have been studied. [30]In a spiral galaxy the interstellar medium makes up 3 to 5 percent of the galaxy’s mass, but within a spiral arm its mass fraction increases to about 20 percent. About 1 percent of the mass of the interstel These formed in the central star’s red giant phase, before it threw off most of its material to become the current hot white dwarf star. Early analysis by our team suggests a low-mass companion star with an eccentric orbit triggered an enhanced release of material from the dying star as it passed close by every 280 years, creating these arcs.” Not all star projectors are scientifically accurate — some are designed to be pleasant ambient lights to be used as kids' night lights or just to create a relaxing atmosphere. However, some models are scientifically accurate and create a planetarium in the comfort of your own home — these include the the Sega Toys Homestar Flux, National Geographic Astro Planetarium and Bresser Junior Astro-Planetarium Deluxe. What is the difference between a star projector and a planetarium?

This particular projector is aimed at children, and the stars it projects aren't scientific like you'd find on the more 'adult' Sega Homestar Flux. But it still features a slide projector and three easy-to-handle discs containing 24 color images taken by the Hubble Telescope. Each disc has a different theme; Nebulas, Spacecraft & Astronauts and Planets & the Moon. Slipher, V. M. (1912). "On the spectrum of the nebula in the Pleiades". Lowell Observatory Bulletin. 1: 26–27. Bibcode: 1912LowOB...2...26S. You'll need to set up your phone's Bluetooth before you start using the projector, but it's easy enough to do so, and the device will be up and running within moments. 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 In 1610, Nicolas-Claude Fabri de Peiresc discovered the Orion Nebula using a telescope. This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659 by Christiaan Huygens, who also believed he was the first person to discover this nebulosity. [11]The colours in the two images represent infrared (invisible) light of different wavelengths emitted by the nebula’s chemical elements and by warm dust particles. By analysing the images, researchers hope to understand better the complex processes behind the formation and evolution of such objects. In comparison to the Atmosphere Smart Galaxy Projector, the Ambience Galaxy & Star Projector has fewer lighting modes available, but it doesn't suffer from it. It offers four colors: blue, green, white and red, and users can blend these colors together using the supplied remote control and adjust the brightness to their specific preference. A beautiful new image of the Ring Nebula captured by the James Webb Space Telescope, which reveals new features in the outer regions of the ring, has been released by ESA, NASA and CSA and an international team co-led by a UCL astronomer.
