«We're at the first point in our history as humans where we might actually have some observations from other planets that we can use to test any of these ideas about life beyond our own,» says Lenardic.

Not exact matches

Recent observations from the Kepler space telescope suggest that planets the size of Jupiter are relatively uncommon around other stars.

In its updated form, it receives e-mail requests from astronomers and automatically executes the observations, searching for planets around other stars and monitoring the flickering of gas falling into black holes.

Dawn's observations are transforming our understanding of how Earth and the other inner planets — Mars, Mercury, and Venus — emerged from the solar system's primordial chaos.

Visible light can't pierce Venus's thick shroud of clouds, so most of what astronomers know about the planet's surface comes from observations in radar and other wavelengths.

Over time, the rings spread out, and the icy bits that drifted farthest from Saturn eventually reached distances where their gravitational attraction for each other could overcome the planet's tidal forces that tended to rip them apart — a process that is still happening today, according to observations by the Cassini spacecraft now touring the Saturn system.

It and other Martian volcanoes act like skate ramps to launch dust up to 75 kilometres above the planet's surface, observations from NASA's Mars Reconnaissance Orbiter (MRO) have revealed.

Hubble now enters a phase of full science observations ranging from studying the population of Kuiper Belt objects at the fringe of our solar system to surveying the birth of planets around other stars.

As of last January, Kepler had identified 2,740 candidate planets, which are steadily being confirmed by follow - up observations from other telescopes.

Previous observations of other hot Jupiter - class planets (HD 189733 b and unpublished data for HD 209458 b) have found that their hot spots may be shifted slightly away from the closest point to the star, possibly due to strong winds moving hot, gaseous material around.

Based on 14 years of radial velocity observations from four ground - based observatories as well as astrometric measurements with the Hubble Space Telescope, the astronomers found that planets «c» and «d» are inclined by 30 + / - 1 degrees with respect to each other is expected to affect theories of how multi-planet systems evolve.

As we know from laboratory experiments, mathematical calculations, and observations of Venus and other planets in the Solar System, greenhouse gases change things in two ways: they trap heat from the sun in the lower atmosphere, thus making the surface of the planet warmer; and they keep heat from rising, thus making the upper atmosphere colder.

In the case of the earth, there is also an immense amount of evidence (from theory, from paleoclimate, even from observations of other planets) to bring to bear.

Three - dimensional (3D) planetary general circulation models (GCMs) derived from the models that we use to project 21st Century changes in Earth's climate can now be used to address outstanding questions about how Earth became and remained habitable despite wide swings in solar radiation, atmospheric chemistry, and other climate forcings; whether these different eras of habitability manifest themselves in signals that might be detected from a great distance; whether and how planets such as Mars and Venus were habitable in the past; how common habitable exoplanets might be; and how we might best answer this question with future observations.
