“Everything about it would be bad,” says Mark Hammergren, an astronomer at Adler Planetarium in Chicago, beginning with your attempt to scoop it up. Despite the fact that white dwarfs are fairly common throughout the universe, the nearest is 8.6 light-years away. Let’s assume, though, that you’ve spent 8.6 years in your light-speed car and that the radiation and heat emanating from the star didn’t kill you on your approach. White dwarfs are extremely dense stars, and their surface gravity is about 100,000 times as strong as Earth’s. “You’d have to get your sample—which would be very hard to carve out—without falling onto the star and getting flattened into a plasma,” Hammergren says. “And even then, the high pressure would cause the hydrogen atoms in your body to fuse into helium.”
(This type of reaction, by the way, is what triggers a hydrogen bomb.)
Then you’d have to worry about confinement. Freeing the sample from its superdense, high-pressure home and bringing it to Earth’s relatively low-pressure environment would cause it to expand explosively without proper containment. But if it didn’t blow up in your face—or vaporize your face, since the stuff’s temperature ranges between 10,000˚ and 100,000˚F—and you somehow got it to your kitchen table, you’d be hard-pressed to feed yourself: A single teaspoon would weigh in excess of five tons. “You’d pop it into your mouth and it would fall unimpeded through your body, carve a channel through your gut, come out through your nether regions, and burrow a hole toward the center of the Earth,” Hammergren says. “The good news is that it’s not quite dense enough to have a strong enough gravitational field to rip you apart from the inside out.”
It probably wouldn’t be worth the trouble anyway, Hammergren laments. White dwarfs are mostly helium or carbon, so your teaspoonful would taste like a whiff of flavorless helium gas or a lick of coal. But if you’re desperate for a taste of star, you don’t really need to travel 8.6 light-years—your fridge is full of the stuff. Most of the elements that make up our bodies and everything around us were formed in the cores of stars and then belched out into the universe over billions of years. Basically everything you eat was once part of a star. Might we recommend some star fruit?

Colorado U.S. Sen. Mark Udall Wednesday took his boldest step yet on the road to a national nuclear renaissance as part of a program designed to combat global warming. He introduced the Nuclear Energy Research Initiative Improvement Act of 2009 in a lengthy speech on the Senate floor in which he acknowledged he was likely stepping on an environmental landmine.
"For some, news that a Udall is speaking favorably about nuclear power will come as a stark - and perhaps unpleasant - surprise. But I also believe public and expert opinion on the risks and benefits of nuclear power has changed," Udall said, referencing the 1979 Three Mile Island power plant meltdown and the industry's struggle to improve its public image in the ensuing three decades.

Russia and Venezuela have signed an agreement to promote the development of nuclear energy for civilian use.
The agreement was signed during a visit by Russian President Dmitry Medvedev to Venezuela's capital, Caracas, on the latest leg of his Latin American tour.
Under the accord, Russia would help Venezuela build a nuclear energy plant. Joint gas projects were also approved.
Military co-operation is also high on the agenda of Mr Medvedev's talks with Venezuelan President Hugo Chavez.
Russian and Venezuelan warships are scheduled to hold joint military exercises later this week.
The Russian vessels, including the flagship missile cruiser Peter the Great and two support vessels, appeared off La Guaira, near Caracas, early on Tuesday.
The destroyer Admiral Chabanenko docked while Venezuelan forces fired a 21-gun salute.
This is first Russian deployment of its kind in the Caribbean since the end of the Cold War.
Russia is already a major arms supplier to Venezuela, with contracts worth some $4.4bn (£2.39bn).

Democrats are trying to make an issue out of comments by Republican presidential candidate John McCain that dismiss Barack Obama's concerns over the safety of nuclear energy.
McCain mimicked his Democratic opponent at a campaign event in Cedar Falls, Iowa, on Oct. 26, saying Obama says nuclear power "has to be safe, environment, blah blah blah," when the two debate over energy policy. McCain went on to say that nuclear power is safe.
Congresswoman Shelley Berkley said Sunday that the remark dismisses safety concerns and insults Nevadans who oppose the construction of a national nuclear waste dump at Yucca Mountain. Most Nevada elected officials oppose the plan.
McCain supports the plan, Obama opposes it.

PARIS, France (AP) -- The French and Venezuelan foreign ministers say they are looking at possibly collaborating on civilian nuclear energy projects in Venezuela.
Venezuelan Foreign Minister Nicolas Maduro and France's Bernard Kouchner speak in Paris on Thursday.
French Foreign Minister Bernard Kouchner also says France would like to use Venezuela as a go-between with Iran in discussions about its disputed nuclear program. However, Kouchner says the Iranians have proved unreceptive to the approach.
Venezuela's Nicolas Maduro told reporters in Paris Thursday his country is interested in going nuclear, adding that humanity's future depends on it.
Kouchner said France "is ready to work with our Venezuelan friends" on the matter.

WASHINGTON (AP) -- The Senate on Wednesday voted to overturn a three-decade ban on atomic trade with India, giving final congressional approval to a landmark U.S.-India nuclear cooperation accord and handing President Bush a rare foreign policy victory in his final months in office.
The accord, which the Senate passed 86-13, will allow American businesses to begin selling nuclear fuel, technology and reactors to India in exchange for safeguards and U.N. inspections at India's civilian, but not military, nuclear plants. The pact, which the House approved Saturday, marks a major shift in U.S. policy toward nuclear-armed India after decades of mutual wariness.
It now goes to Bush for his signature.
Bush hailed the Senate's vote, saying in a statement that the legislation approving the accord "will strengthen our global nuclear nonproliferation efforts, protect the environment, create jobs and assist India in meeting its growing energy needs in a responsible manner."
Congressional approval caps an aggressive three-year diplomatic and political push by the Bush administration, which portrays the pact as the cornerstone of new ties with a democratic Asian power that long has maintained what administration officials consider a responsible nuclear program. Administration officials also have championed the opportunities for U.S. companies to do business in India's multibillion-dollar nuclear market.
Sen. Richard Lugar, R-Ind., said the pact protects U.S. national security and nonproliferation efforts while building "a strategic partnership with a nation that shares our democratic values and will exert increasing influence on the world stage."
"With a well-educated middle class that is larger than the entire U.S. population, India can be an anchor of stability in Asia and an engine of global economic growth," Lugar said.
Opponents say lawmakers, eager to leave Washington to campaign for the November elections, rushed consideration of a complicated deal that they said could spark a nuclear arms race in Asia. The extra fuel the measure provides, they say, could boost India's nuclear bomb stockpile by freeing up its domestic fuel for weapons.
Sen. Byron Dorgan, D-N.D., said the accord "will almost certainly expand the production of nuclear weapons by India" and help dismantle the architecture of the Nuclear Non-Proliferation Treaty, the global agreement that provides civilian nuclear trade in exchange for a pledge from nations not to pursue nuclear weapons.WASHINGTON (AP) -- The Senate on Wednesday voted to overturn a three-decade ban on... more
