Each year the RAS recognizes outstanding achievement in astronomy and geophysics by the award of medals and prizes. Candidates are nominated by Fellows and the awards made by a committee of Fellows, ensuring that these scientists have earned the respect and admiration of their peers in the research community. The Gold Medal for Astronomy is awarded to Prof. In a series of papers starting in , Joe Silk gave key predictions — later verified experimentally — on the angular fluctuations expected in the temperature of the cosmic microwave background, including the effects of curved space, and then incorporating cold dark matter.

He also predicted the damping scale of the baryon condensations, now called Silk damping. These predictions motivated many experiments searching for dark matter. With Dekel in he wrote a paper on the origin of dwarf galaxies incorporating cold dark matter and feedback from exploding stars; this too had a major influence on the subsequent direction of the field. In another heavily cited paper with Rees he developed the concept of AGN feedback and the relationship between the masses of the central black hole and the host galaxy.

Silk has made many other contributions to astronomy, for example to the theory of star formation, high-energy astrophysics, and the physics of the intergalactic medium. The Gold Medal for Geophysics is awarded to Prof.

NASA again delays launch of James Webb Space Telescope

Astronomers hope IXPE will reveal the spin of black holes, and yield new discoveries about the extreme magnetic fields around a special type of neutron star called magnetars. In order to obtain the sensitivity required for the X-ray research, the IXPE observatory will host three identical X-ray telescopes that will be extended after launch on a foot 4-meter boom.

The team at Marshall will assemble, calibrate and test the mirrors before shipping the flight units to Ball Aerospace for integration on the spacecraft, Hertz said. So not only was it a schedule hit, it was also a budget hit.

Received: 6 December Accepted: 6 April The concept EHI design consists of two or three satellites in polar or equatorial circular medium-Earth orbits MEOs with slightly different radii. On long baselines, where the signal-to-noise ratio may be low, fringes could be detected assuming that the system is sufficiently phase stable and the satellite orbits can be reconstructed with sufficient accuracy.

Averaging visibilities accumulated over multiple epochs of observations could then help improving the image quality. With three satellites instead of two, closure phases could be used for imaging. Our preliminary study of the EHI concept shows that it is potentially of high scientific value. It could be used to measure black hole shadows much more precisely than with ground-based VLBI, allowing for stronger tests of general relativity and accretion models.

More than ever, Chile has become a major international center for ground-based astronomy. Given the strong scientific and human connection between France and Chile for several decades, the Lab plays a central role to nurture this collaborative endeavour between both countries. Fields of Research : Over the years, the Lab has contributed to the development of important key projects in the field of modern astronomy including the study of stellar formation, planetary formation and evolution, exoplanets, and the death of stars.

Candidates must inquire to their home institution about the feasibility and applicable conditions for the transfer before applying to the positions. French FCLA members are therefore requested to actively develop new collaborations and maintain existing ones. Visits and exchanges between Chile and France are also strongly encouraged. Application forms should include a joined research statement, a plan for on-going and foreseen research collaborations in Chile, and brief CVs.

Applications from all fields of investigations in astronomy are welcome not only the ones described in Fields or Research. Information about Astronomy at the three Universities can be found here:. The initial deadline for application is set to October 30th, and evaluation will start immediately after. Both C1 and C2 applications will be received until the positions are filled. For more information please contact Mrs. We strongly encourage initial contacts before applying.

These positions are open for a minimum stay of 1 year, and up to 3 years.

Arianespace to launch a French astronomy mission in 2019: the EyeSat Triple Cubesat

The moon. It casts its cool glow over romantic strolls, inspires poetry, catches the eye sometimes in broad daylight and sends some astronomers fleeing indoors until the satellite once again departs the night sky. In this edition of Mobile Astronomy, we’ll explore Earth’s nearest natural satellite with apps that show where it is and what phase it’s in now, and in the future ; apps with maps labeling the lowlands, mountains and craters; apps highlighting exploration missions; and even some free digital books about the moon that you can have with you at the eyepiece or just relaxing at the cottage this summer.

The moon, also known as Luna, is Earth’s nearest celestial neighbor. At a mean distance of approximately , miles , kilometers , the light from the moon which is reflected sunlight takes 1.

Balancing astronomical visions with budgetary realities

The introductory undergraduate astronomy classes have labs attached to them, and those labs are run by grad students. The Head TA is a grad student assigned to ensure that those teaching labs have all the information they need. We have a copy of the Lab manual online as a PDF. In addition to just knowing the answers, it helps to know where students tend to make mistakes.

Astronomy lessons requires some cleverness, so does handling both Ariane and Rebecca at the same time. Nice + Sexy = cuteness. This is.

This decision is based on a recently completed schedule risk assessment of the remaining integration and test activities before launch. The new launch date factors include the impacts of augmented safety precautions, reduced on-site personnel and shift-work disruption. Now that Webb has been assembled into its final form, the telescope will continue undergoing a final set of environmental tests before it is shipped to its launch site in Kourou, French Guiana. This week, electrical testing on Webb was successfully completed.

Acoustics and vibration environmental tests of the full observatory are scheduled to start in August. Ensuring that every element of the telescope functions properly before it gets to space is critical to its success. The Canadian Space Agency is a proud partner of Webb, contributing two important elements of the most complex and powerful space telescope ever built.

Thanks to that contribution, Canadian scientists will take part in this exciting science mission that promises to change our understanding of the universe and our place in it.

Telescopes Used

The mission is aimed at observing at least 1, known exoplanets using the transit method , studying and characterising the planets’ chemical composition and thermal structures. ARIEL will observe 1, planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. The SVM is shaped as a ‘sandwich’ structure, consisting of three aluminum V-Grooves and three pairs of low conductivity fibreglass bipod struts supporting the PLM.

The ARIEL telescope’s assembly is an off-axis Cassegrain telescope followed by a third parabolic mirror to recollimate the beam.

You used to need charts, maps, and telescopes to gaze at the night sky and understand what you were looking at. Backyard stargazers use apps to discover a wealth of information on the location and identity of planets , stars, and galaxies — no telescope needed. The best astronomy apps use the gyroscope and compass in your smartphone or tablet, along with date, time, and location services, to determine your whereabouts.

Because the Earth rotates every 24 hours and the planets orbit around the sun every Your location dictates which constellations are visible. The Messier List , for example — researched and published by Charles Messier in — includes deep-sky objects viewable from the Northern Hemisphere and is a popular feature for such apps. Here are a few of the many cross-platform iOS and Android apps we discovered.

Just hold up your phone, use a pinch-to-zoom gesture, and have the app pinpoint whatever is up there. After determining your position, the app locates stars, the moon, planets, and constellations. The sky map updates dynamically as you move your phone around the block, neighborhood, or region to see twinkling stars, nebulae, meteors, and sunset glow.

Detailed information covers sky objects, equatorial and azimuthal grids, the Milky Way Galaxy, sunrise and sunset, eclipse simulation, and more. With SkySafari, all you have to do is hold your device up to the sky and let the app quickly assemble planets, constellations, satellites, stars, and deep sky objects.

You can use the app to animate a variety of celestial events such as meteor showers, comet approaches, transits, and conjunctions. SkySafari lets you simulate the night sky from anywhere on Earth and move backward and forward in time.
