Humanity marked 20 years of continuous habitation of the orbiting International Space Station on November 2, 2020. We’re celebrating the milestone by posting a variety of articles about the ISS during this historic year. In our latest Word Search puzzle, we’ve hidden 39 words related to the ISS. The words may be placed horizontal, vertical, …

Will we someday colonize space? Will our children visit other planets? To achieve goals like these, we’ll need to crack one crucial challenge: how to feed ourselves for long periods away from Earth. A trip to Mars would take months, and exploring the depths of the galaxy would take even longer. Provision of nutritious food …

NOVEMBER 22, 2020: The Apollo-type asteroid (7753) 1988 XB will pass 0.066 AU from Earth. The best visibility will be next week when it travels west-northwestward through Leo, Cancer, and Gemini and will be 15th magnitude. Close approaches by near-Earth asteroids are the subject of this week’s “Special Topics” presentation.   NOVEMBER 25, 2005: JAXA’s Hayabusa …

Perihelion: 2013 November 28.78, q = 0.012 AU  I mentioned in the “Special Topics” presentation on “Great Comets” that such objects come by about once a decade, on average. Comet NEOWISE C/2020 F3, which appeared back in July, could perhaps be considered a borderline “Great” comet, but prior to that, the last “Great Comet” for those of …

In the Week 2 “Special Topics” presentation I discussed the history and recognition of near-Earth asteroids and described some of the early observed encounters by these objects. What could perhaps be considered the most remarkable of these asteroids was a 10th-magnitude fast-moving object discovered on October 28, 1937, by Karl Reinmuth at Heidelberg Observatory in …

When SpaceX launches the Falcon 9 rocket with the Crew Dragon Resilience spacecraft atop it from historic Launch Complex 39A, the Commercial Crew Program (CCP) will finally have reached fruition.

The United States and Canada are joining forces to encourage a new generation of astronauts. The two countries have cooperated on space exploration since soon after NASA, the U.S. space agency, was founded in 1958. Canada sends astronauts on NASA space missions, and it supplies technology for the International Space Station, among other space efforts. …

If you like numbers, you will love March 14, 2015. When written as a numerical date, it’s 3/14/15, corresponding to the first five digits of pi (3.1415) — a once-in-a-century coincidence! Pi Day, which would have been the 136th birthday of Albert Einstein, is a great excuse to eat pie, and to appreciate how important …

The Histories by Herodotus (484BC to 425BC) offers a remarkable window into the world as it was known to the ancient Greeks in the mid-fifth century BC. Almost as interesting as what they knew, however, is what they did not know. This sets the baseline for the remarkable advances in their understanding over the next …

Ever since humans could look up to see the sky, we have been amazed by its beauty and untold mysteries. Naturally then, astronomy is often described as the oldest of the sciences, inspiring people for thousands of years. Celestial phenomena are featured in prehistoric cave paintings.

Across a brief 10-day period covering mid to late July, the United Arab Emirates, China, and the United States each launched their own mission to explore Mars. For the UAE and China, it is their first solo attempt to reach the Red Planet, whereas the U.S. is continuing to build upon a legacy of success …

The planet Mars is probably the most studied planet, other than Earth, in our solar system. Like Earth, Mars is a terrestrial planet, as opposed to a gas planet like Jupiter for example. Mars is often referred to as the Red Planet, due to the brownish-red color of its surface caused by iron oxide in …

Gazing at the Universe

Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the Universe is scarier than a black hole. Black holes – regions in space where gravity is so strong that nothing can escape – are a hot topic in the news these days. Half of the 2020 Nobel Prize in …

Until now, everything we’ve known about black holes — celestial objects with intense gravitation — has been from theories and illustrations. Now, thanks to an international collaboration called the Event Horizon Telescope (EHT), a cosmic portrait of a supermassive black hole exists. At the center of the galaxy Messier 87 (M87) in the Virgo constellation, the …

For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nicknamed, are only hypothetical. But new research from NASA’s Spitzer Space Telescope has identified one such candidate, seemingly looking billions …
