There are a variety of formalized summer-research internships for physics and astronomy students, spread across all disciplines and across the country.

Goucher offers its own summer-research program, to which you can apply by speaking directly with your professors.   

The most well-known off-campus program is the REU (Research Experience for Undergrads), which is sponsored by the National Science Foundation (NSF). These are competitive programs hosted at a variety of labs and institutions, which will provide you a stipend (and sometimes living accommodations) to perform research over 8-10 weeks in the summer.  Applications are typically due in late-December through mid-February.  The list of programs is always growing, but can be found at the link above, or http://www.nsf.gov/crssprgm/reu.

A great resource for the REU and other programs can be found at this blog page, hosted by the University of Illinois.  

Below are a list of some of the more popular programs.

Here are some direct links to institutions in the area:

Here are some international research internships (a great way to do research and satisfy your study-abroad requirements):

  • The US Department of Energy (DOE) and the National Institute for Nuclear Physics - Italy (INFN) operate a program dedicated to the exchange of US and Italian students in science and engineering. INFN, one of the leading organization worldwide promoting basic scientific research, is involved with cutting-edge activities in all major INFN-DoE areas of interest: Particle Physics, Astroparticle Physics, Nuclear Physics, Theoretical Physics and Detector Physics (see http://www.infn.it/). US students are invited to apply for a two-month summer internship during which they will join an INFN research team. Positions are available at a variety of INFN sites throughout Italy. Candidates must be enrolled as students at a US university and they must have begun, at the time of application, at least the third year of a US University curriculum in physics, engineering or computing science. A small grant will be provided to cover travel and living expenses.
  • RISE (Germany) is a summer internship program for undergraduate students from the United States, Canada and the UK in the fields of biology, chemistry, physics, earth sciences and engineering. RISE offers unique opportunities for Bachelor students to work with research groups at universities and top research institutions across Germany for a period of 2 to 3 months during the summer. RISE interns are matched with doctoral students whom they assist and who serve as their mentors. The working language will be English. All scholarship holders receive stipends from the DAAD to help cover living expenses, while partner universities & research institutes provide housing assistance.
  • UTRIP (Japan) is an intensive summer research program targeted at undergraduates who have a keen interest in pursuing an M.S. or Ph.D. degree in the future. During the program, the participants receive intensive instruction and guidance on conducting research from renowned faculty members belonging to the GSS's five departments, physics, astronomy, chemistry, earth & planetary science, and biological sciences. The program is open to students who are currently enrolled in their junior or senior years at an accredited college or university outside of Japan, and who are majoring in a natural science or related field.
  • The Summer Research Internship (SRI) Programme (Singapore) is a university wide Research Programme initiated to stimulate a culture of research for the overseas undergraduates. Participants for this programme will develop research interest, strong sense of cross-cultural intelligence, gain a network of friends and a better understanding of our nation. Eligible overseas undergraduate students will be given an allowance, and are expected to fulfill a 8-week research attachment comprising project work at Nanyang Technological University (NTU), and presentation of their research project at a closing ceremony. All participants will receive a certificate issued by NTU upon completion of the programme.
  • The Leiden/ESA Astrophysics Program for Summer Students (Holland)(LEAPS)is an opportunity for students with an interest in astronomy and astrophysics to perform a 10-12 week summer research project in collaboration with a research scientist from Leiden Observatory or ESA. The program is open to all students not currently engaged in a Ph.D. program, although we are most interested in students at the senior-undergraduate or masters level who are enthusiastic about research in astrophysics.
