Life may have evolved on at least three planets within a newly discovered solar system 39 light years from Earth. Astronomers at the NASA have discovered no less than seven roughly Earth-sized worlds orbiting a dwarf star in the system. Scientists had previously identified a tiny number of "exoplanets", which are believed to have the qualities needed to support life. However, the new system contains an unprecedented(前所未有) number of Earth-sized, probably rocky planets, and is being acknowledged as an "accelerated leap forward" in the search for extraterrestrial (外星球的)life.

Three of the new planets are said to be particularly promising because there might exist oceans. Thomas Zurbuchen, associate administrator of NASA, told a press conference in Washington: "This gives us a hint that finding a second Earth is not a matter of 'if', but 'when'."

The planets were discovered using NASA's Spitzer Space Telescope, which was able to track how fast each of the planets crossed the star Trappist-l and completed an orbit. From this the research team calculated how far the planets were from their star, and therefore how likely they are to be habitable.

NASA's Hubble Space Telescope is already being used to search for atmospheres around the planets. Future telescopes, including the proposed European Extremely Large Telescope and the James Webb Space Telescope, may be powerful enough to discover markers of life, such as oxygen in the atmospheres of exoplanets.

Astronomers believe there could be as many as 40 billion potentially habitable worlds in our galaxy, the Milky Way. Prof Zurbuchen said that now was a "gold-rush phase" in the search for these exoplanets.

Money is stressful. For the seventh year in a row, the APA’s annual Stress in America survey found that money is the top source of stress for American adults. More than a quarter of Americans say they feel stressed about money most or all of the time. Only 30 percent rate their financial security as high, and more than two-thirds believe that more money would make them happier.People commonly deal with anxiety by avoiding whatever it is that makes them anxious. Unfortunately, if you avoid dealing with your finances, you’ll likely create more financial problems, and more anxiety, in the long term.

Money matters are too important to ignore. Financial inability is linked to money mismanagement and to debt. Debt, in turn, is associated with lower self-confidence, lower productivity and greater stress. Unsurprisingly, research has also linked financial pressure to desperation (绝望).

We develop our beliefs and attitudes about money early in life. Often, we aren’t even consciously aware of what our beliefs are, let alone where we learned them. If you’re dealing with financial avoidance or financial rejection, it can help to think critically about the money beliefs you learned in childhood. Think about what your parents taught you about money. Talk to family members about their money beliefs. Then try to challenge your existing beliefs about money.

Many people feel embarrassed about their debt, ashamed that they let bank statements pile up unread. But that shame keeps you stuck. Try to move past the self-blame so you can take some concrete steps toward financial health.
