  • Milky Way Lost & Found (8/15/2018) - Have you seen the Milky Way? You may think that you have, but are you sure? Unless you live in an extremely remote area, or you’ve visited one, then you probably haven’t seen our own galaxy, the Milky Way, very well, or at all. Worse yet, you may not even realize that it’s missing. The … Continue reading Milky Way Lost & Found

Encyclopædia Britannica

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. — Wikipedia

Science


Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all phenomena that originate outside Earth’s atmosphere are within the purview of astronomy.

Astronomy is one of the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, Maya, and many ancient indigenous peoples of the Americas performed methodical observations of the night sky. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars, but professional astronomy is now often considered to be synonymous with astrophysics. — Wikipedia

Encyclopædia Britannica

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of the astronomical objects, rather than their positions or motions in space. Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics. — Wikipedia

  • Dark, Deep & Spooky… (8/8/2017) - Today’s physics is “probably” not the kind of thing that you, or at least your parents and grandparents, learned about in school (unless you happen to be a Physicist). Even the most casual science buff knows that today it’s all about exotic stuff like dark matter (NASA), ghost particles (FermiLab) and “spooky action at a … Continue reading Dark, Deep & Spooky…
  • Enterprise (1/22/2017) - Star Trek fans, take notice. Here’s a cool new 360° video that takes you where you’ve never gone before… or well, at least not outside of a 2D screen. It’s a grand up-close tour of the Enterprise, and it was posted by CBS to promote the series. Check it out! (This is a 360° YouTube … Continue reading Enterprise

  • Exoplanet Junket (6/2/2018) - I’m on a vacation of sorts, so it’s no surprise that stories about travel tend to catch my eye. However, it is surprising if the story happens to be about something that NASA’s done. This week NASA released a new project that they’ve dubbed the Exoplanet Travel Bureau. The core of the project consists of … Continue reading Exoplanet Junket
  • Get Lost in Space! (9/14/2018) - Way back in August, in anticipation of the start of a new school year, I set out to update the pages on this site related to space.

On the other hand, the 3D/360°/AR/VR content front has been “relatively” static (unless you love Halloween’esque horror, of course).

  • Super Bowl of Astronomy (1/15/2018) - The annual meeting of the American Astronomical Society, a.k.a. the “Super Bowl of Astronomy” was held in Washington DC last week.
