Neil deGrasse Tyson: ‘How Much Would You Pay for the Universe?’

“Nobody’s dream­ing about tomor­row any­more,” says astro­physi­cist Neil deGrasse Tyson in this com­pelling lit­tle video on the decline of the Amer­i­can space pro­gram. “After we stopped going to the moon, it all end­ed. We stopped dream­ing.” The video was put togeth­er by Evan Schurr with mate­r­i­al from var­i­ous sources. In it, Tyson asks us to imag­ine the pos­si­bil­i­ties for tomor­row if NASA’s bud­get were increased to just one pen­ny for every tax dol­lar. It’s a point he raised ear­li­er this month before a U.S. Sen­ate com­mit­tee (read the full tes­ti­mo­ny here), when he said:

The 2008 bank bailout of $750 bil­lion was greater than all the mon­ey NASA had received in its half-cen­tu­ry his­to­ry; two years’ U.S. mil­i­tary spend­ing exceeds it as well. Right now, NASA’s annu­al bud­get is half a pen­ny on your tax dol­lar. For twice that–a pen­ny on a dollar–we can trans­form the coun­try from a sullen, dispir­it­ed nation, weary of eco­nom­ic strug­gle, to one where it has reclaimed its 20th cen­tu­ry birthright to dream of tomor­row.

Neil deGrasse Tyson Remembers His First Meeting with Carl Sagan

Carl Sagan left a big void when he died in 1996. His elo­quence, his pas­sion for explain­ing sci­ence to a wider pub­lic, made him a major cul­tur­al fig­ure in late 20th cen­tu­ry Amer­i­ca. Now a new voice is emerg­ing. Neil deGrasse Tyson, like Sagan, is an astronomer and physi­cist with a remark­able gift for speak­ing about the beau­ty and impor­tance of sci­ence. Like Sagan, he hosts a PBS tele­vi­sion pro­gram (NOVA Sci­en­ceNOW) and appears fre­quent­ly on talk shows. The pass­ing of the torch will become obvi­ous next year, when Tyson hosts the sequel to Sagan’s ground-break­ing 1980 TV series, Cos­mos. Tyson’s con­nec­tion to Sagan actu­al­ly began at a very young age. In the video clip above, Tyson tells Ted Simons of the region­al PBS show Ari­zona Hori­zon the sto­ry of a remark­able act of gen­eros­i­ty by Sagan when Tyson was only a teenag­er.

Earth-Size Tornadoes On The Sun

What a sight to behold. Ear­li­er this month, NASA’s Solar Dynam­ics Obser­va­to­ry (SDO) beamed back stun­ning images of the sun’s plas­ma mov­ing vio­lent­ly around the star’s mag­net­ic field for 30 some hours, cre­at­ing a tor­na­do as large as the Earth itself, with gusts reach­ing up to 300,000 miles per hour. That’s accord­ing to Ter­ry Kucera, a solar physi­cist with NASA’s God­dard Space Flight Cen­ter. NPR has more on the mak­ings of solar storms.

The Birth of the Moon: How Did It Get There in the First Place?

The Moon is a mys­tery. For all its familiarity–the reg­u­lar­i­ty of its phas­es, the fact that every­where on Earth it looks the same–the Moon has always been an enig­ma, a lumi­nous ques­tion mark rolling across the night sky.

In this new video from Cos­mic Jour­neys, we learn about some of the lat­est sci­en­tif­ic research into the struc­ture and his­to­ry of the Moon. In par­tic­u­lar, we learn the lat­est ideas on what is per­haps the great­est of lunar mys­ter­ies: the ques­tion of how the Moon got there in the first place.

The lead­ing can­di­date for an answer is the Giant Impact Hypoth­e­sis, which posits that some­time in the ear­ly stage of the Solar System–about four and a half bil­lion years ago–a large pro­to-Earth col­lid­ed with a Mars-sized body named “Theia,” caus­ing a huge cloud of mate­r­i­al from both bod­ies to fly out into space. Some of the mate­r­i­al remained in the Earth­’s orbit and coa­lesced into the Moon. It’s a fas­ci­nat­ing hypoth­e­sis.

The Far Side of Moon: A Rare Glimpse from NASA

Here’s some­thing you don’t see every night: the far side of the Moon, pho­tographed by one of NASA’s Grav­i­ty Recov­ery and Inte­ri­or Lab­o­ra­to­ry (GRAIL) space­craft.

The Moon is “tidal­ly locked” in its orbit around the Earth, mean­ing its rota­tion­al and orbital peri­ods are exact­ly syn­chro­nized. As a result, we always see the same view of the Moon no mat­ter when or where (on Earth) we look at it. In this inter­est­ing video, released last week by NASA, we get a rare glimpse of the Moon’s oth­er side, start­ing with the north pole and mov­ing toward the heav­i­ly cratered south.

The video was cap­tured on Jan­u­ary 19 by the “MoonKAM” aboard one of a pair of GRAIL space­craft that were launched last Fall and began orbit­ing the Moon on New Year’s Eve and New Year’s Day. The pri­ma­ry mis­sion of GRAIL is to study the Moon’s inte­ri­or struc­ture and to learn more about its ther­mal evo­lu­tion.

GRAIL is also the first plan­e­tary mis­sion by NASA to car­ry instru­ments ded­i­cat­ed sole­ly to edu­ca­tion and pub­lic out­reach. The “KAM” in “MoonKAM” stands for Knowl­edge Acquired by Mid­dle school stu­dents. The pro­gram, led by for­mer astro­naut Sal­ly Ride, will engage fifth- to eighth-graders from across the coun­try in select­ing tar­get areas on the lunar sur­face to pho­to­graph and study. Edu­ca­tors inter­est­ed in par­tic­i­pat­ing can reg­is­ter at the MoonKAM web­site. To learn more about the video and GRAIL, see the NASA news release.

Apocalypse Not Quite Yet: Why Solar Storms Won’t End the World in 2012

With the largest solar storm since 2005 light­ing up the night skies this week after a pair of solar flares sent streams of charged par­ti­cles hurtling toward the earth, prophets of doom have been light­ing up the Inter­net.

Bob Thiel, a self-described “Church His­to­ry and End Times Exam­in­er” and author of 2012 and the Rise of the Secret Sectwrote yes­ter­day: “Worse solar flares will ulti­mate­ly hap­pen after the ‘Great Tribu­la­tion’ begins (Rev­e­la­tion 16: 8–9), and one or more that affect satel­lites and elec­tric­i­ty could hap­pen even today.” Hmm. Inter­est­ing.

Although very seri­ous ques­tions do exist about the readi­ness of our elec­tric pow­er grid and satel­lite infra­struc­ture to with­stand a major solar storm like the one in 1859 that short­ed out tele­graph wires and caused auro­rae so bright a crew of gold min­ers in Col­orado report­ed­ly got out of bed in the mid­dle of the night to cook break­fast, the cur­rent increase in solar activ­i­ty is part of a reg­u­lar 11-year cycle and pos­es no spe­cial risk, accord­ing to NASA helio­physi­cist Alex Young. (See the video above.) And any­way, Young says, the peak isn’t expect­ed to hit until 2014, well after the Mayan cal­en­dar has run its course.

For an inter­est­ing dis­cus­sion about the past week’s solar activ­i­ty you can lis­ten to Phil Plait, author of Dis­cov­er Mag­a­zine’“Bad Astron­o­my” blog, in an inter­view yes­ter­day with Patt Mor­ri­son of Los Ange­les pub­lic radio KPCC. And for a look at the earth-direct­ed coro­nal mass ejec­tion of Jan­u­ary 22, you can watch anoth­er NASA video below.

Watch A Brief History of Time, Errol Morris’ Film About the Life & Work of Stephen Hawking

Bril­liant but unmo­ti­vat­ed, Stephen Hawk­ing was a 21-year-old PhD stu­dent at Cam­bridge when he first noticed some­thing was wrong. He was falling down a lot, and drop­ping things. He went into the hos­pi­tal for tests, and learned he had amy­otroph­ic lat­er­al scle­ro­sis, or ALS. The doc­tors told him he would grad­u­al­ly lose con­trol of every mus­cle in his body.

“My dreams at that time were rather dis­turbed,” Hawk­ing said. “Before my con­di­tion had been diag­nosed, I had been very bored with life. There had not seemed to be any­thing worth doing. But short­ly after I came out of hos­pi­tal, I dreamt that I was going to be exe­cut­ed. I sud­den­ly real­ized that there were a lot of worth­while things I could do if I were reprieved.”

The doc­tors gave the young man two and a half years to live. That was in ear­ly 1963. Over the next half cen­tu­ry, Hawk­ing defied all odds and went on to become one of the most cel­e­brat­ed sci­en­tists of the era, mak­ing major con­tri­bu­tions to quan­tum cos­mol­o­gy and the under­stand­ing of black holes. Along the way, the wheel­chair-bound Hawk­ing became a cul­tur­al icon, a sym­bol of dis­em­bod­ied intel­lect and indomitable spir­it.

This com­ing Sun­day, 49 years after his grim diag­no­sis, Hawk­ing will turn 70. A sci­en­tif­ic con­fer­ence in his hon­or got under­way today at the Uni­ver­si­ty of Cam­bridge’s Cen­tre for The­o­ret­i­cal Cos­mol­o­gy, and will cul­mi­nate on Sun­day with a pub­lic sym­po­sium, “The State of the Uni­verse,” fea­tur­ing some of the world’s great­est astronomers and physi­cists, includ­ing Mar­tin Rees, Kip Thorne and Saul Perl­mut­ter. You can watch live stream­ing video of the events at the offi­cial web­site.

To help cel­e­brate, we present Errol Mor­ris’s 1992 film of A Brief His­to­ry of Time (above), Hawk­ing’s best­selling book.  Mor­ris weaves biog­ra­phy in with the sci­ence, inter­view­ing mem­bers of Hawk­ing’s family–his moth­er, sis­ter and aunt–along with friends and col­leagues, includ­ing Roger Pen­rose, Den­nis Scia­ma and John Archibald Wheel­er.

A Brief His­to­ry of Time was Mor­ris’s first film as a direc­tor-for-hire (he was recruit­ed by Steven Spiel­berg for Amblin Enter­tain­ment), which cre­at­ed some dif­fi­cul­ties, but Mor­ris was pleased with the out­come. He lat­er said, “It’s actu­al­ly one of the most beau­ti­ful films I ever shot.” The film won the Grand Jury Prize for Doc­u­men­tary Film­mak­ing and the Doc­u­men­tary Film­mak­er’s Tro­phy at the Sun­dance Film Fes­ti­val.

In 1992 Mor­ris told the New York Times Mag­a­zine that A Brief His­to­ry of Time was “less cere­bral and more mov­ing” than any­thing he had worked on before. “This feel­ing of time, of aging, of mor­tal­i­ty com­bined with this search for the most basic and deep ques­tions about the world around us and our­selves,” Mor­ris said, “is pret­ty per­sua­sive stuff.” Find it list­ed in our Free Movies Online col­lec­tion, with­in the Doc­u­men­tary sec­tion.

Animated Video Shows Curiosity, NASA’s Mars Rover, in Dramatic Action

In late Novem­ber, NASA’s Curios­i­ty, the world’s biggest extrater­res­tri­al rover, began rock­et­ing toward Mars (see pho­tos of the launch here) in search of any hint that the red plan­et might have pro­vid­ed a home for micro­scop­ic life. The Curios­i­ty will even­tu­al­ly reach Mars in August after cov­er­ing 345 mil­lion miles. Ear­li­er this year, an artist released a rather dra­mat­ic ani­ma­tion depict­ing key moments in the mis­sion — the voy­age, the land­ing (don’t miss this part!), the explo­ration, and all of the rest. It’s anoth­er can­di­date for our col­lec­tion of Great Sci­ence Videos.
