What could create a huge hole the clouds? Such a hole, likely hundreds of meters across, was photographed last month from a driveway near Mobile, Alabama, USA. Very unusual to see, hole-punch clouds like this are still the topic of meteorological speculation. A leading hypothesis holds that the hole-punch cloud is caused by falling ice-crystals.
Earths Recent Climate Spiral
22.08.2022
Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global temperature of the Earth has increased by nearly one degree Celsius.
Earth's Temperature
30.01.1997
What's the temperature outside? No matter where you are on Earth, the above map can tell you. This global montage was created using the temperature data from numerous satellites orbiting the Earth. This...
Aurora Crown the Earth
27.05.1996
What do aurora look like from space? The POLAR spacecraft answered this by photographing an auroral oval surrounding the north pole of the Earth, causing displays on both the night and day side. The auroral sub-storm, pictured in false-color above, developed within 15 minutes and may have lasted as long as on hour.
The Earths Magnetic Field
25.11.2002
Why does the Earth have a magnetic field? The electrical conductivity of the molten plasma of the Earth's core should be able to damp the current magnetic field in only thousands of years. Yet our five billion year old Earth clearly causes magnets to point to (defined) north.
Impact! 65 Million Years Ago
12.10.1997
What killed the dinosaurs? Their sudden disappearance 65 million years ago, along with about 70 percent of all species then living on Earth, is known as the K-T event (Cretaceous-Tertiary Mass Extinction event). Geologists and paleontologists often entertain the idea of a large asteroid
The International Space Station Expands Yet Again
8.12.2002
The developing International Space Station (ISS) has changed its appearance yet again. Earlier this month the Space Shuttle Endeavor visited the ISS and installed the fourth of eleven pieces that will compose the Integrated Truss Structure. The new P-1 Truss is visible on the left, below the extended solar panels.
Beefing Up the International Space Station
17.12.2002
The International Space Station (ISS) will be the largest human-made object ever to orbit the Earth. The station is so large that it could not be launched all at once -- it is being built piecemeal with large sections added continually by flights of the Space Shuttle.
The Newly Expanded International Space Station
23.04.2002
What does the developing International Space Station (ISS) look like now? After delivering and deploying a crucial first backbone-like component last week, the Space Shuttle Atlantis took an inspection lap around the space station. The newly installed truss is visible toward the center of the above image.
Neutron Star Earth
16.06.1995
If the Earth could somehow be transformed to the ultra-high density of a neutron star , it might appear as it does in the above computer generated figure. Due to the very strong gravitational field, the neutron star distorts light from the background sky greatly. If you look closely, two
