Astronomers have captured the best image ever of planet formation around an infant star as part of the testing and verification process for the Atacama Large Millimeter/submillimeter Array’s (ALMA) new high-resolution capabilities.
CERNland is the virtual theme park developed to bring the excitement of CERN's research to a young audience aged between 7 and 12. CERNland is designed to show children what we do at CERN and inspire them with some physics at the same time. CERNland contains games on all topics related to the CERN activity.
Instructions on how to build a model of a comet
Comets are considered to be time capsules containing information about the conditions of the early Solar System. In order to understand what they are, where they come from, and their influence on the evolution of Earth, it is necessary to find out what material they contain. This demonstration and practical activity, along with the resulting discussion, gives an insight into the chemical constituents of comets. An additional activity (extension), which looks at the impact processes on Earth as well as calculations of the kinetic energy involved, is included.
NASA's Hubble Space Telescope has revisited the famous Pillars of Creation, revealing a sharper and wider view of the structures in this visible-light image.
Astronomers combined several Hubble exposures to assemble the wider view. The towering pillars are about 5 light-years tall. The dark, finger-like feature at bottom right may be a smaller version of the giant pillars. The new image was taken with Hubble's versatile and sharp-eyed Wide Field Camera 3.
This activity asks you to explore how planet formation is connected to star formation. Although you learned about star formation in Unit 3, you haven’t yet studied the process of planet formation. The purpose of this activity is to give you an opportunity to use your intuition and logic to make deductions about what might happen next to the matter that is left over after a star has formed.
Topics
Description
Explore how heating and cooling iron, brick, and water adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and changes through your system.
Sample Learning Goals
Topics
Description
Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.
Sample Learning Goals
Topics
Description
Visualize the gravitational force that two objects exert on each other. Change properties of the objects in order to see how it changes the gravity force.
