So most people have no idea of the difference between like, an emission nebula and a planetary nebula.

Loading Small Magellanic Clouds

The quot Dust in born again Planetary Nebulae quot , and quot Edge on Dust Disks in Planetary Nebulae quot programmes received observing time on the Infrared Space Observatory (ISO) satellite.

Clouds such as this have been identified previously with the progenitors of current galaxies.

We need our theatre greats right here.

(b) Eruptive variables irregular B and Be stars (Pleione, 5 Dra, OT Gem), Orion variables with diffuse nebulae, T Tau variables, flash stars connected with diffuse nebulae (V 389 Ori), ultraviolet Cet flare type stars, rapid irregular variables (RW Aur type), novae and supernovae, Haro Herbig objects with short time variations, RCB type stars etc.

(a) Stellar variability (i.e. asteroseismology) on, inter alia, T Tauri, Be and B, W CMa, δ Scuti, Ap and Am type stars, red giant and dwarf stars, planetary nebulae and post novae

This geostationary satellite is able to capture visible light images of clouds, 24 hour infrared images of clouds and pictures of vapour distribution, in addition to being capable of broadcasting climate pictures.

Magellanic Clouds

And we can see places where stars are forming, like the Eagle Nebula. We see stars dying.

The first project aims at observing the centres of some old, evolved planetary nebulae (PNe) harbouring a hot central star which has recently ejected highly processed hydrogen poor material.

And we can also study chemical composition and physical parameters of stars, galaxies, nebulae.

The satellite data serve to improve weather forecasting on an operational basis, and are used in the International Satellite Cloud Climatology Project (ISCCP) and the Global Precipitation Climatology Project (GPCP) of WMO.

It also distributes by facsimile the cloud images obtained.

I have to talk about astronomy without showing you any single image of nebulae or galaxies, etc.

The second project investigates evolved PNe which show a bipolar morphology with a pronounced dust disk, seen edge on.

The International Satellite Cloud Climatology Project is producing long term climatological records of global cloud amount and properties, as well as radiation flux data from the international array of geostationary meteorological satellites and operational polar orbiting satellites.

In June 1994, two scientists using the HST discovered disks of protoplanetary dust around stars in the Orion Nebula region of the Milky Way galaxy.

It also distributes by facsimile the cloud image charts thus obtained.

And now, folks, bright and early on this beautiful sunny day, flowers are fresh from the rain, and there isn't a cloud in the sky.

The programme relates to the study of cold objects such as planets, comets or cold clouds, the physics of interstellar space, the physiochemistry of interstellar dust, the formation of stars, the variation from one galaxy to another and the study of the primitive evolution of the galaxies.

Vital information was exchanged on the cometary path, the cometary dust environment and experiment design.

During the 1980s, emphasis was placed on the development of a geostationary meteorological satellite, the FY 2.

Although the telescope was designed primarily for photometric observation studies of variable stars, it also allows for the observation of comets and asteroids and the study of interstellar, interplanetary and atmospheric dust.

It demonstrates mixing of lithologies from very different regions of the solar nebula.

It's a condensable in the atmosphere, and so recognizing this circumstance brought to the fore a whole world of bizarre possibilities. You can have methane clouds, OK, and above those clouds, you have this hundreds of kilometers of haze, which prevent any sunlight from getting to the surface.

Furthermore, satellite data provide information on cold cloud duration and the state of vegetation.

This is ed sullivan reminding you that the colgatepalmolive company also brings you starstudded entertainment on our show on most of these same stations.

Don't get too cocksure.

Gumo for clouds in the sky.

(a) Intrinsic variables low mass red giants with mass loss and irregular red giants or supergiants (e.g. Mira and mu Cep), RR Lyr stars and the Blasko effect, pre white dwarfs, RV Tau stars (e.g. 89 Her), dust shell stars in post AGB phase (bipolar flow), central stars of planetary nebulae and their ejected mass

Intensified efforts are being made to develop the China Brazil Earth Resources Satellite, a small satellite for observing the colour of ocean water, and the Fengyun 1 polar orbiting satellite. The development of these satellites will substantially enhance China s capabilities in satellite data collection.

GMS observes cloud coverage and temperatures of sea surface and cloud top, and collects meteorological data from aircraft, buoys and meteorological observation stations in remote areas.

Several interstellar clouds have been observed and the presence of the condensation of very cold interstellar matter unknown so far has been revealed.
