What inspires scientists and innovators? On July 19, First Comes the Dream, a celebration of New York City’s emergence as a premier technology center, brought luminaries from science, technology, and media to the Museum to find out.
Co-hosted by the Museum with leading tech blog Gizmodo and social networking app Foursquare, the evening began in the Hayden Planetarium with remarks from Museum President Ellen Futter, NASA Administrator Charles Bolden, and New York City Deputy Mayor Robert Steel before launching the awe-struck audience on a tour of the universe with the Museum’s Director of Astrovisualization Carter Emmart.
Next, Dr. Neil deGrasse Tyson, director of the Museum’s Hayden Planetarium, sat down for an interview with iO9’s Annalee Newitz in the Cullman Hall of the Universe. In the video below, find out what sparked Dr. Tyson’s interest in astronomy and what he thinks the future of space exploration might hold.

A new model shows how an elusive type of black hole can form in the gas surrounding its supermassive counterparts.
In research published in the Monthly Notices of the Royal Astronomical Society, scientists from the American Museum of Natural History, the City University of New York (CUNY), the Jet Propulsion Laboratory of the California Institute of Technology, and the Harvard-Smithsonian Center for Astrophysics propose that intermediate-mass black holes—light-swallowing celestial objects with masses ranging from hundreds to many thousands of times the mass of the Sun—can grow in the gas disks around supermassive black holes in the centers of galaxies. The physical mechanism parallels the model astrophysicists use to describe the growth of giant planets in the gas disks surrounding stars.

In 1950, as part of a publicity campaign, the Hayden Planetarium began accepting reservations for what was billed as the first trip into space. After ads appeared in newspapers and the story was picked up by BBC broadcaster Alistair Cooke, letters poured in from as near as Newark and as far as Northumberland, with requests to book trips to the Moon, Mars, and beyond.
Some were accompanied by elaborate drawings of spacecraft, others by offers to serve as crewmembers on the flight. All came from applicants who wrote passionately about becoming the first to experience a trip to outer space, and the result is a treasure trove of letters that capture the public fascination with space exploration, a selection of which are now available for viewing on the Museum’s Beyond Planet Earth: The Future of Space Exploration site.

Astrophysicist Jackie Faherty is blogging about the upcoming transit of Venus, which will take place next week. In her first post, she explains what the transit is, when it occurs, where she will be observing it—and where New Yorkers can catch a glimpse of the phenomenon.
A rare astronomical event is upon us: our sister planet Venus is about to transit our Sun. Depending on your geographic location, this means that the distant planet will glide across the face of the Sun appearing as a small black dot for several hours. Just like the Moon will sometimes pass between the Earth and the Sun, causing a solar eclipse, so do the innermost planets Venus and Mercury. However, since Venus and Mercury are many times more distant to us than the Moon, and since their orbits are not perfectly aligned with that of the Earth, transits of the inner planets are far more rare than solar eclipses and the shadows they cast are smaller. But the event is no less dramatic and unfolds over several hours rather than mere minutes.

Four nights a year, the streets of Manhattan’s grid become the site for a spectacular sunset phenomenon known as Manhattanhenge. Below are answers to frequently asked questions about this event.
What is Manhattanhenge?
As Director of the Hayden Planetarium Neil deGrasse Tyson, who discovered the phenomenon and coined the term “Manhattanhenge,” explains in his Hayden Planetarium blog, Manhattanhenge takes place “when the setting Sun aligns precisely with the Manhattan street grid, creating a radiant glow of light across Manhattan’s brick and steel canyons, simultaneously illuminating both the north and south sides of every cross street of the borough’s grid. A rare and beautiful sight.”
