Scientists at CERN first produced antimatter in 1996 in an experiment that created antihydrogen.

欧洲核子研究组织科学家1996年在一次制造反氢实验首次制造出了反物质。

Last year ALPHA used a magnetic trap to hold on to antihydrogen atoms for a record 16 minutes.

去年ALPHA成功地使用磁阱，创纪录地令反氢原子存活长达16分钟之久。

He said that the research ruled out that gravity pushes antihydrogen away from the center of the Earth.

他说，这项研究排除了重力将反氢推离地球可性。

Later, thanks to advanced technologies, physicists were able to obtain not just antiparticles, but whole anti-atoms, anti helium, and antihydrogen.

后来，由先进技术，物理学家不到反粒子，而且到整个反原子、反氦和反氢。

During the experiment, researchers said the antihydrogen particles were moving around at a speed of about 100 meters a second.

在实验，研究人员表示，反氢粒子移动速度约为每秒100米。

Measuring the light spectrum of antihydrogen is a key part of solving that mystery.

测量反氢光谱是解开这个谜团关键部分。

And a great way to test that idea is by comparing the light coming from hydrogen and antihydrogen.

测试这个想法一个好方法是比较来自氢和反氢光。

But what they found was that the antihydrogen emitted the exact same spectrum of light as hydrogen.

但他们发现，反氢分子发出光谱与氢分子完全相同。

So, in 2011, antihydrogen lasted as long as 1,000 seconds and in 2014, eighty anti hydrogen atoms were created for the purpose of a detailed study.

因此，在2011年，反氢原子持续了一千秒，而在2014年，为了一项详细研究，八十个反氢原子被创造出来。

Working out of the CERN lab in Switzerland, these researchers figured out how to capture about 14 antihydrogen atoms within a 15-minute cycle.

在瑞士 CERN 实验室工作这些研究人员想出了如何在 15 分钟周期内捕获大约 14 个反氢原子。

Previous research had only managed to capture about 1.2 antihydrogen atoms in a cycle, so the team had a lot more to work with.

之前研究只在一个循环捕获大约 1.2 个反氢原子，因此该团队还有更多工作要做。

And if antimatter really is an exact mirror image of matter, then the positrons in antihydrogen should give off the exact same spectrum as the electrons in plain old regular hydrogen.

如果反物质真是物质精确镜像，那么反氢正电子应该发出与普通氢电子完全相同光谱。

And in a paper published this week in the journal Nature, an international team of more than 50 researchers announced that they’d detected the spectrum of light coming from the antimatter form of a hydrogen atom, aka antihydrogen.

在本周发表在《自然》杂志上一篇论文，一个由 50 多名研究人员组成国际团队宣布， 他们检测到了来自氢原子反物质形式（即反氢原子）光谱。
