1. A European spacecraft took off today to spearhead the search for another
"Earth" among the stars.
2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from
the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm.
3. Corot, short for convection rotation and planetary transits, is the first
instrument capable of finding small rocky planets beyond the solar system. Any
such planet situated in the right orbit stands a good chance of having liquid
water on its surface, and quite possibly life, although a leading scientist
involved in the project said it was unlikely to find "any little green men".
4. Developed by the French space agency, CNES, and partnered by the European
Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will
monitor around 120,000 stars with its 27cm telescope from a polar orbit 514
miles above the Earth. Over two and a half years, it will focus on five to six
different areas of the sky, measuring the brightness of about 10,000 stars every
512 seconds.
5. "At the present moment we are hoping to find out more about the nature of
planets around stars which are potential habitats. We are looking at habitable
planets, not inhabited planets. We are not going to find any little green men,"
Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since
its inception, told the BBC Radio 4 Today programme.
6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could
develop an atmosphere and, if they are the right distance from their parent
star, they could have water".
7. To search for planets, the telescope will look for the dimming of
starlight caused when an object passes in front of a star, known as a "transit".
Although it will take more sophisticated space telescopes planned in the next 10
years to confirm the presence of an Earth-like planet with oxygen and liquid
water, Corot will let scientists know where to point their lenses.
8. Measurements of minute changes in brightness will enable scientists to
detect giant Jupiter-like gas planets as well as small rocky ones. It is the
rocky planets - that could be no bigger than about twice the size of the Earth -
which will cause the most excitement. Scientists expect to find between 10 and
40 of these smaller planets.
9. Corot will also probe into stellar interiors by studying the acoustic
waves that ripple across the surface of stars, a technique called
"asteroseismology".
10. The nature of the ripples allows astronomers to calculate a star’s
precise mass, age and chemical composition.
11. "A planet passing in front of a star can be detected by the fall in light
from that star. Small oscillations of the star also produce changes in the light
emitted, which reveal what the star is made of and how they are structured
internally. This data will provide a major boost to our understanding of how
stars form and evolve," Prof Roxburgh said.
12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting
a star other than the Sun - more than 200 others have been found by ground-based
observatories.
13. Until now the usual method of finding exoplanets has been to detect the
"wobble" their gravity imparts on parent stars. But only giant gaseous planets
bigger than Jupiter can be found this way, and they are unlikely to harbour
life.
14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five
interlinked space telescopes that will not only spot small rocky planets, but
analyse their atmospheres for signs of biological activity.
15. At around the same time, the US space agency, Nasa, will launch
Terrestrial Planet Finder, another space telescope designed to locate Earth-like
planets.

1. Corot is an instrument which
(A) can help to search for certain planets
(B) is used to find planets in the orbit
(C) can locate planets with human beings

Selling Digital Music without Copy-protection Makes Sense
A. It was uncharacteristically low-key for the industry’s greatest showman.
But the essay published this week by Steve Jobs, the boss of Apple, on his
firm’s website under the unassuming title “Thoughts on Music” has nonetheless
provoked a vigorous debate about the future of digital music, which Apple
dominates with its iPod music-player and iTunes music-store. At issue is
“digital rights management” (DRM)—the technology guarding downloaded music
against theft. Since there is no common standard for DRM, it also has the
side-effect that songs purchased for one type of music-player may not work on
another. Apple’s DRM system, called FairPlay, is the most widespread. So it came
as a surprise when Mr. Jobs called for DRM for digital music to be
abolished.
B. This is a change of tack for Apple. It has come under fire from European
regulators who claim that its refusal to license FairPlay to other firms has
“locked in” customers. Since music from the iTunes store cannot be played on
non-iPod music-players (at least not without a lot of fiddling), any iTunes
buyer will be deterred from switching to a device made by a rival firm, such as
Sony or Microsoft. When French lawmakers drafted a bill last year compelling
Apple to open up FairPlay to rivals, the company warned of “state-sponsored
piracy”. Only DRM, it implied, could keep the pirates at bay.
C. This week Mr. Jobs gave another explanation for his former defence of DRM:
the record companies made him do it. They would make their music available to
the iTunes store only if Apple agreed to protect it using DRM. They can still
withdraw their catalogues if the DRM system is compromised. Apple cannot license
FairPlay to others, says Mr Jobs, because it would depend on them to produce
security fixes promptly. All DRM does is restrict consumer choice and provide a
barrier to entry, says Mr Jobs; without it there would be far more stores and
players, and far more innovation. So, he suggests, why not do away with DRM and
sell music unprotected? “This is clearly the best alternative for consumers,” he
declares, “and Apple would embrace it in a heartbeat.”
D. Why the sudden change of heart? Mr Jobs seems chiefly concerned with
getting Europe’s regulators off his back. Rather than complaining to Apple about
its use of DRM, he suggests, “those unhappy with the current situation should
redirect their energies towards persuading the music companies to sell their
music DRM-free.” Two and a half of the four big record companies, he helpfully
points out, are European-owned. Mr Jobs also hopes to paint himself as a
consumer champion. Apple resents accusations that it has become the Microsoft of
digital music.
E. Apple can afford to embrace open competition in music players and online
stores. Consumers would gravitate to the best player and the best store, and at
the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to
the iPod. Since only 3% of the music in a typical iTunes library is protected,
most of it can already be used on other players today, he notes. (And even the
protected tracks can be burned onto a CD and then re-ripped.) So Apple’s
dominance evidently depends far more on branding and ease of use than
DRM-related “lock in”.
F. The music giants are trying DRM-free downloads. Lots of smaller labels
already sell music that way. Having seen which way the wind is blowing, Mr Jobs
now wants to be seen not as DRM’s defender, but as a consumer champion who
helped in its downfall. Wouldn’t it lead to a surge in piracy? No, because most
music is still sold unprotected on CDs, people wishing to steal music already
can do so. Indeed, scrapping DRM would probably increase online-music sales by
reducing confusion and incompatibility. With the leading online store, Apple
would benefit most. Mr Jobs’s argument, in short, is transparently self-serving.
It also happens to be right.
